If a transwoman wins a race/event, every other biological female gets pushed back 1 space. In the first instance, the woman in 2nd misses out on the title (potential) prize money, and opportunities and sponsorship that might come from winning. The woman in 4th place has now missed a medal placing (and the potential prize/opportunities that come with that). That's 2 women already. Why are their training and career prospects less important?
Word.
You can only believe in this being ok if you believe, deep down, that male people's choices, feelings and self expression matter more than the equality of females.
It's male supremacism, and those pushing this need to own it and be ready to explain and defend it if they seriously want a world where being born female means being a subhuman servant class to male born people (regardless of how that person chooses to identify.)
The sex based thinking always, always underpins the loudly protested spiel about sex not being a thing (except to sort the mummies, nannies, carers and social workers from the service users), no one knows what sex anyone is (but I know who wins and why, and who has to enable or else) and TWAW (except a special kind of women who get to be listened to and prioritised instead of told to shut up, serve, smile and here's a rape threat.
