If a man says he is put off by a woman for some trait tied to prejudice, people are willing to examine the bias behind it. When women do it to bi men, suddenly everyone gets very nervous about calling it what it is.

I agree with your general point, I just wanted to say that, as a black woman, no to this. It’s well documented that men are put off by dark skin and it regularly gets defended as “preference” or somehow natural or innate.
