I can’t get why a dude who decides he wants to be woman does something so unfeminine as to use his male bone structure and muscle mass to whip women in sports. But why even bother trying to understand these nut-jobs?
Same reason that non-monogamous people wanted “marriage”.
Wave it in your face.
They men doing this don’t want to compete, they want to win.
I believe there as an example in a race - the time that the tranny won with set a new record for the school’s women’s sports - and would not have finished within the top 10 in men’s sports.
