Yeah, the "this never happens" defence is as weak as the "trans oppression is just like racism defence. Luckily, and sadly, I have experience of both.
Each of the points I make about athletics and surgery and homophobic abuse is linked. Just go to the article, click the links, and stop pretending that "nobody is saying" the things they absolutely are saying. It's so ridiculous to deny things when the evidence for them is a click away.
And no. I don't sound like a person railing against desegregation. Saying that males and females are different is not like saying that black people aren't human. The only way it might make sense if you believe that black people are white people "born in the wrong body." But this doesn't sound quite so cute, does it?
