For every female identifying trans person present at all at top-level sport, they have already dominated at all lower levels of competition to get there - removing opportunity from women and girls as they go.
Every year multiple 15-16 year old schoolboys run a 100 metre sprint time faster than the women’s world record. There is no comparison or fair competition, ever.
Sport is categorised by sex, not gender.
The USA conflating the two en-masse is the biggest problem here.
No one believes it’s possible to change sex, so there’s no justification at all to uproot all our sports competitions to please a tiny portion of the populace.
Talking about inclusion: 99.9% of the population are already excluded from high level sport by not having the genetics and opportunities. You can still play and enjoy sport, it’s fine.
