Let’s make a bet. We combine men and women’s sports. There will eventually be no women in sports, because, even though the top ranking women can beat some, or even most, men, they cannot beat the top men.
If this wasn’t the case, we wouldn’t see such a wide gap in points/speed/weights/whatever between top men and women in their respective sport.
There may still be trans people in said sport (though I doubt it, but maybe), but there will definitely be no women.
Let’s say this does happen. Then what do we do for women in sports, who are now, by default, completely excluded?
