It’s quite simple really. Feminists have told us for decades that there is no difference between male and female, that women can do anything a man can do.
These biological male athletes competing against biological female athletes have blown that lie right out of the water.
And thus with that lie being blown right out of the water, some feminists (mostly lesbians at this point) are starting to retreat from that position, believe it or not. Some have.
Secondly, the trans people, at odds more and more with some lesbians, are still plodding forward ignoring the reality that a male thinking he is a female does not make it so.
Don't be silly every action TV show has 100 lb women regularly beat up a couple 200+ pound men.
