People are allowed to have whatever standard they want. An obese woman is allowed to have the standard that she only wants to date a 6'2 jacked guy. An obese man is allowed to only want to date supermodels. People must be realistic about their ability to find a partner that meets their standards and face the consequences of having those standards.

Saying that it's "hypocritical" for a high N man to not want to date high N women is like saying that it's "hypocritical" for escorts to not want to date John's even though they both engaged in prostitution. You might say "there is a difference between selling sex and buying sex", to which I would argue that there is a difference between being man seeking casual sex and being a woman seeking casual sex. The experiences that men and women have when seeking casual sex aren't comparable and should be seen as two different experiences much as the buying and selling of sex.

An escort may have a myriad of reasons for not wanting to date Johns. PTSD and emotional trauma from engaging in that work being one of them. A guy who had a history of using casual sex as a desperate attempt to validate himself and experienced trauma from being reduced to his body parts in a way that women do not experience on the dating apps is absolutely justified in not wanting to date a high N woman who didn't give a damn about whether or not the men she slept with found her attractive.
