Why can men impose beauty standards on women but not vice versa?

I kinda see this all the time. I know the reverse can happen too, but personally I met so many men both in real life and online that listed off things what makes a woman a woman, and if she does not tick the box, she is a try hard, not a real woman, a loser, underdeveloped or a lesbian, a man in disguise or woke. And when my friend (who is hot by the way) told her her own standarts, that she preffers men about 5'8 foot till 6 foot with a nice face and hair, the same men started raging that women are shallow and unreal about their standarts. Even though they also wanted the stereotypical 90-60-90 type of woman with a nice face.
