I have several thoughts on this bullshit:
In sports there’s always going to be someone better. Just look at the Olympics where a dozen of the best athletes around the globe compete and only the top three would be given medals. So this is bad sportsmanship.
2. You cannot tell who is a “real” woman/girl just by looking at someone. Someone being muscular doesn’t mean they’re actually male. Grow the hell up.
3. Schools should not be prying into students’ privacy, period. Even if the athlete was trans, the school should not have the authority to make that information public.
