I will say that the male incel community is fascinating for me. Probably a rare instance of intense male masochism on display. They harbor simplistic outlooks about the dating world. Men are apparently always the victims. Biology is apparently set to be on hard mode for the man. Much like feminists they seem to hold onto that victimhood and do not want to let it go. Yet reality is more nuanced than that. Both genders have their pros and cons when it comes to the dating scene.
Some of the incel type videos on YouTube are amusing. Where they show what "Chads" look like. I mean its not so much I disagree that attraction is mostly biological and universal, but most people men and women know that they're not going to be getting the cream of the crop when it comes to mates. Some of these YouTube videos, they review dating shows on television. If a man with a weak chin walks in the incel narrator is like "ohhh.. noo.. this guy has already lost. Game over for him". Lol.. they tend to say worse than that but I'd like to keep it CF appropriate, lol.
I suspect most incels are just angry that they can only attract low-tier women. Yet I suspect if most worked on themselves they could get someone at least semi-cute. The chances of me ever marrying a supermodel is slim, but that's alright. I never had any expectations for that. As long as your man or woman has some feminine/masculine traits you should be fine. Some people are just too greedy.
Involuntary celibacy is a stupid concept. Put in a little work and you can find someone. There are women with fetishes who find disfigurement/burn victims attractive. If the elephant man were alive today and used the internet he could find someone lol. So even the extremes really have no excuse. While I agree there is mostly a universal set of traits men and women go for, evolution is also about mutations. There are people who will find all kinds of things attractive. The pool might be smaller, but its there. The best part is, people with strange attractions can be traditionally very attractive themselves.
