You are still fighting a straw man here. Please point me to where I said all sports should be desegregated? It’s a very complicated issue and trying to segregate into 2 strict groups by sex at birth is a very messy, very imperfect solution. What some doctor thought was going on when they looked between a newborn’s legs is just not nearly as important as some other factors.

To give an example of a split I would be in favor of: Segregation based on factors relevant to the sport (like height and how far people can throw a ball for basketball). You can split into as many groups as needed and hey, if you’re right it’ll work out to an even gender split anyway, right? This just happens to be a way more inclusive way of doing things also avoids the weird situation of minors being harassed about their gender expression. Unless of course you want to specifically make people uncomfortable and want to exclude certain people. But that’s not the point you’re arguing, right?
