Yes, but then you also have to note the mothers are teaching their daughters the same thing. I agree, it's stupid and sexist, but blaming it on the men isn't really the solution. A good portion of problems feminists complain about are caused by other women, or isn't just the mans fault. Although some are.
Also, the traditional role of the father as disciplinarian has already changed. The majority of child abuse and domestic abuse is on fault of the woman, and in my area the mother is usually the one that disciplines the child. At least it seems that way, as the mother often yells at the children rather then the father if the child is doing something wrong, so I can assume that at home it's probably likewise.
Sexual harassment is a big issue, agreed. If a man at an office says a woman looks good, she can complain that he was sexually harassing her and he could get in trouble. I've heard of this happening fairly often lately. Now I can understand comments like "Nice ass" and stuff like that, but just saying "Hi, you look good today" seems like a compliment that should be taken with good will rather then assume the person has bad intent. Likewise, women can sexually harass men just as well. If a woman keeps trying to make moves on a guy, how is that different from a guy trying to make moves on a woman constantly? The majority of men do not sexually harass women, and the majority of women do not harass men. The 80% discrepancy is the cause of the problem, not the result.
As for what girls and boys are taught at a young age, I disagree on your viewpoint. They are raised differently, granted, but there are pros and cons for each. Boys are raised often to not cry and to deal with things on their own. They're taught to be independent and to focus hard on getting things done and being productive. But there are cons, as emotional problems are often dismissed as them being sissies. Any sign that they're weak, and they're picked on at school. Growing up as a male is often a large amount of competition between each other to be the strongest, smartest, and the best overall.
As for girls, they're far more pampered as a kid. I'm not being sexist, it's true. Their emotional problems are far more catered to, if they get hurt they are taken care of rather then told to deal with it, and if someone is bullying them physically someone will almost always step in. In school, if a guy pushes another guy nobody could care less. If a guy pushes a girl, immediately at least 3 guys will take a step toward him. But while they're pampered, they're not pushed as hard to focus on things such as education, sports, or to get a job. They're taught to have proper manners and to be good and probably to play a musical instrument of some kind. But recently, they've also being taught more and more to be independent. This shows a slight shift in how they're raised, but it's not enough yet.
Evidence of the differences in how they're raised shows in the higher occurrence of suicide and depression in males. For every 1 female that commits suicide, 3.5 males commit suicide. Out of all suicides, 7/10 are white males(not sure if this matters or not, so I included it.) This almost had a nation men's day started to raise awareness about suicide rates in males, but feminists shut it down saying it was for sexist pigs and that the men were just sissies(sigh).
The difference I believe starts with how they're raised. But the question is how to raise them?
Should we stop pampering girls emotional needs and push them harder to do well in school, sports, and education?
Or should we start pampering guys and stop pushing them as hard to succeed?
If we don't pamper anybody, then everything is one massive competition where every weakness will drastically decrease your chance of success.
But if we pamper everybody, then the drive to succeed isn't as high. The motivation to get into things like physics is less, and they will settle more to just get jobs.
