It's simple...The perception that it's much easier for women to get the attention of and affection of the opposite sex...Add in to the fact that women can use their looks and sex as leverage in life to a much higher extent than men can..So now, you have plenty of men who hold contempt for women on these merits.
It's not really a perception
The term "puzzy is power" exists for a reason
But besides that, you just stated that women in general can use their looks and sex a leverage moreseo than men which I agree with
But the issue is that even though a lot of women can parlay their body/sex appeal into opportunities, not all women are able to do this just off the strength of their looks
Yet a large percentage females seem to think that they are "dimes" as evidenced by the female in the OP, even though a person's attractiveness rating comes from the people observing them, not the person themselves
I just find it odd that females will go out of their way to use looks to judge men who never asked to be judged by their looks(ex Travis Scott, Lil' Wayne) and call them all sorts of ugly, yet when a female displays herself for the sole purpose of being judged on her looks, a man is a bully and displaying "toxic masculinity" if he doesn't stroke her fragile ego
More and more I'm seeing dudes being shamed just because they don't find random female attractive, even though "attractiveness" is mostly preferential in the first place
