It's actually a woman who's competing with men that's taking testosterone. The man who's competing with women is presumably on testosterone blockers (but will still have much higher T than a genetic woman and also have different bone structure and retain some muscle mass as a result of going through puberty as a man). In the latter case, I'm ok with it because it's a sort of poetic justice in light of the insistence within the past generation that it's sexist for men to do anything without women. Now men are systematically infiltrating women-only spaces and they can't say boo because they retardedly went along with tranny acceptance.
