You didn't address this to anyone in particular so I'm going to put in my 2 cents.
One of the things I've noticed on this site is that you can call a person just about anything you want as long as it is implied or put diplomatically, and it is not a direct statement. For example, this quote:
...pretty much called you (or whoever was being spoken to), a 'fuckin scientific know it all idiot'. But since it was not directly said to you, there is plausible deniability. 'Oh, I didn't mean him, just, you know, some other guy.'
Or if someone says "I think you went inside the Sphere you need some psychological help." Here again, 'Oh, I'm not saying he is crazy, it was just a thought I was having'.
Most of your comments were subtle, but when you made your 'jackass' comment, there was no plausible deniability. You called him a jackass.
To me there is really not much of a difference. I've been called lots of things on this site, but it is usually put like "Perhaps you are a dumbshit with no ability at all". I think they get away with it because they didn't just straight out say "You are a dumbshit!"
I may be wrong but I think the reason you got called out was because you did not diplomatically call him a jackass.
