Because the entire concept of "performance class" is absolutely stupid.

That doesn't disprove my point, but it does prove that you don't have the patience for a civilized argument.

I don't even know how to argue against it because the entire concept is dumb. Sport is about competition, who is the best etc. Your performance class bullshit would kill that off.

Be sure you tell all the E-Sports people and professional sports players that you think ranked competition is "dumb", lol~. Sounds like you want to mix the amateur and professional leagues too, right?

Actually, sports were segregated because the average women can't compete with the average man

If that were the case, sports would have always been segregated.

Here in reality, professional baseball was only segregated after Jackie Mitchell struck out Babe Ruth and Lou Gherig at an exhibition game in April 1932. Her contract was voided by the league's commissioner the next day.

The idea that women can't compete with men is a myth that was manufactured to defend fragile male egos.

Caster Semenya has a condition causing her to have much higher testosterone levels than other women. That has nothing to do with trans people. I do agree that excluding her because of this is unfair.

Let me get this straight, you think that a cis woman who was excluded from sports for high testosterone doesn't have anything to do with the trans women who you want to exclude from sports for having testosterone?

My dude, you're the one demanding the sort of gender testing that resulted in what you yourself acknowledge is unfair exclusion.
