Right. But if she was a Democrat, and for transgender inclusion at any cost, that could only be honest discussion.

Bruce Jenner was the Worlds top male decathlete, AKA "World's greatest athlete" in 1976; She is now Caitlyn Jenner. She may have some perspective your future uncle Cathy does not yet have

I've stated a number of times that I do not know how to categorize intersex athletes. Say the World's top male decathlete transitioning to female...would that extreme example be outside of the realm of possibilities? (Caitlyn Jenner by the way, doesn't think it would be fair to allow transgender females in female sports) If you are going to make up new rules or change old ones, you need to look at potential consequences. Anyone not open to discussing plausibilities, and consider it dishonest discussion...should take no part in setting rules for competitive sports.

I was asked for the sake of discussion how I defined biological males and biological females. That was how I could best summarize what I meant by those terms. Otherwise points taken.

At the most competitive levels for many sports I don't know how you can avoid it, whether for direct screening or CY's suggestion of evaluating on a case by case basis. At recreational levels I think it would be unnecessarily intrusive. I certainly hope so.

The fact that some individuals with XX chromosomes can have higher than typical testosterone, or other typically male advantages, is problematic, but that should not be used as a reason to include XY individuals in female sports. Great. When are they moving them in? Or wait...are they not moving them in? Are they considering your rights as well?

If someone wanted to live in your house, or they would be depressed, should they be given the right to live there? Or do you have to say sorry, no, but wish them well?

Yes. Except I don't believe they should be subjected to unhealthy drug protocols in order to compete.

Those with XX chromosomes clearly biologically female. Those with XY chromosomes clearly biologically male. Those with atypical chromosomes not at all clear.

Yes. Have you read any of the links in this thread? No. Not that one. That was against 15 year olds. I take that one with a grain of salt. Formal games are played against teenagers. Age around 17 years old with the skill level chosen so the women won't be dominated. It happens in ice hockey also, regularly when getting ready to compete at the highest women's level. We are talking about biological males competing against biological females. Can you not even admit that?

You seem to think the worst motives of anyone who doesn't agree with your position. I don't blame transgender athletes for choosing to change, or if adults "altering their chemistry". Altering their chemistry is between them and their doctor. I do blame you, and your ilk, for forcing them to change their chemistry and/or incentivizing changing it, and for belittling the importance of female sports. At the point a doctor is targeting an individual's chemistry to meet a rule rather than the best for the individuals health...they are no longer acting as a doctor. Unless of course...the observer actually watches sports. I mean...you had no clue whatsoever at the start of this thread that the top Women's Soccer Team in the World (The US Team), most obviously a team of elite athletes, could be dominated by a top male teenage team. You haven't observed jack.

Oversimplifying your take. would that be like allowing school integration, gay or interracial marriage, washroom of choice use, or drinking from the same fountains, but only if certain individuals altered there body chemistry to meet conditions you deemed necessary, or alter their skin tone enough that you deem acceptable? Of course you would not, so why are you doing the equivalent here? Why are you on board with it? Why do you find it totally fine? Can you not see that it's a terrible compromise, both unhealthy and impossible to do fairly, and that competitive female sports are in fact threatened, with or without it? Or do you have some psychological impediment to understanding any of that?

In the category of their choice? Because any remaining male anatomical and physiological advantages can't be accurately evaluated and handicapped. Nor should it be, when the handicap[s resort to any unhealthy use of drugs.

Thanks. So diminishing to 4%. Much more in line with what I would expect. And again with swimming, guessing "superficially" that buoyancy is the main factor in the male advantage diminishing faster with distance, and eventually leading to a female advantage. We both agree their is a trend, regardless if you eventually prove correct with regard to running (I doubt it) Can we not also agree these stem from anatomical and physiological differences of males and females? What are they basing it on otherwise? Can we not also agree that averages are less critical than the elite range of the distribution? Who cares if Hussein Bolt, for example, is at a natural disadvantage against top female marathoners? Is there a distance he should potentially be allowed to run competitively against top females? All of this should be decided, ideally, on the playing field, keeping the "judging" of individual cases out of it. Obviously that ideal can't be perfect, with the difficulties in categorizing intersex athletes. For typical transgenders it really isn't that hard, outside of having to tell a small but vulnerable part of our population they can't play in the category of their choice. They are human. They are transgenders. It's not a term I would have expected you would want to promote for them, reinforcing that they are different from "normal" humans. (I'm not suggesting you think that way) Plus the term is kind of taken: https://en.wikipedia.org/wiki/Transhuman#:~:text=Transhuman%2C or trans-human%2C,beyond those of standard humans. "Transhuman, or trans-human, is the concept of an intermediary form between human and posthuman.[1] In other words, a transhuman is a being that resembles a human in most respects but who has powers and abilities beyond those of standard humans.[2] " Just my opinion. Carry on using the term if you don't see the harm. I'm certainly not a good judge of what people might find offensive a priori.

With respect, I don't think that's a suitable term.

Had to look it up...I was thinking "wouldn't that be during ejaculation?"😀

Definitely post it. I don't want to see the book...

I think most of the top coaches, and many of their athletes, would take the Cole's Notes version on the biology and science, and after weighing it against their experience...get most of it pretty close to correct. Right. So where is the data? What is the distribution used for the claim you are supporting?

I think there is some truth to what you are saying but I think it mostly due to the fact that, on average, female athletes are lighter than men. This may diminish male advantage as you point out, but if you look at elite level records it's fairly obvious that males still maintain a significant advantage. In any case your link really didn't support your/their conclusion, other than assure us they had taken in a lot of data. It may be that women do have a physiological advantage, but it certainly hasn't been proven, and the link doesn't give the evidence to support it. But even if World Records are only indicative of highly trained athletes at elite levels as you suggest...those are the level of performances that should be considered for setting rules for the highest levels of competition. For recreational athletes the competitive subset of the rules are less critical.

This doesn't seem to be true at elite levels. https://en.wikipedia.org/wiki/Ultramarathon Men[edit] Event Record Athlete Date Place 50 km 2:43:38 Thompson Magawana (RSA) 12 Apr 1988 Claremont, South Africa 100 km 6:09:14 Nao Kazami (JPN) 24 Jun 2018 Yubetsu-Saroma-Tokoro, Japan 100 miles 11:28:03 Oleg Kharitonov (RUS) 20 Oct 2002 London, United Kingdom 1000 km 5d 16:17:00 Yiannis Kouros (GRE) 26 Nov – 2 Dec 1984 Colac, Australia 1000 miles 10d 10:30:36 Yiannis Kouros (GRE) 20–30 May 1988 New York City, USA 6 hours 97.200 km Donald Ritchie (GBR) 28 Oct 1978 London, United Kingdom 12 hours 163.785 km Zach Bitter (USA) 14 Dec 2013 Phoenix, USA 24 hours 303.506 km Yiannis Kouros (GRE) 4–5 Oct 1997 Adelaide, Australia 48 hours 473.495 km Yiannis Kouros (GRE) 3–5 May 1996 Surgères, France 6 days 1036.800 km Yiannis Kouros (AUS)[a] 20–26 Nov 2005 Colac, Australia ^ Kouros had Australian citizenship for part of his running career.

Current model for the Universe I think has it that if it is infinite now, it also was at the big bang, only denser at that point. The Observable Universe has never been infinite.

You're probably right...but that's more glass half empty...

I'm pretty sure the raccoons that take over after we mess up will evolve to the point they have a fighting chance. That's my glass half full...😀

There are a lot of people of various backgrounds, from many parts of the world, that come to post here. For many it takes time to understand what the Mods here deem acceptable and what they do not, and accept that the arbitrary rules are fair or could be. In fact up to that point many might argue, and many have, that they aren't. It's not always clear that no disrespect was stated or intended, when it's pretty clear no respect was intended, and different words hold different connotations for many people. "Ignorance" is one of them. Just my $0.02 and probably overpriced.

Maybe is puzzling to you...yet not addressed by anyone here...because no one here made such a bizarre claim...at least that I'm aware of. The fact that elite teenage boys teams could dominate your National women's soccer and ice hockey teams has been discussed...sorry if seemed to you that someone thought any biologically male team could. Or why even have the category in the first place? Let's go back to the 1800s. After all...nice girls don't want to compete.
