Do you have sources to cite on that? Because this honestly sounds like an incel talking point. The idea that it's ok for women to judge and reject men -- for being short, or any other number of male-oriented deficiencies -- but men are not similarly free to reject women based on their appearance. It's bullshit and it doesn't really exist. Anecdotally, I've never once seen someone be judged for not wanting to date someone no matter how shallow the reason. It's just another way in which these men are claiming to be unfairly victimized in the dating world.
