It’s not a cultural thing, it’s a weird manosphere thing. If you read the guy’s comment history, it quickly becomes obvious why he is single and can’t keep a relationship. If you don’t feel like it, which I don’t blame you, I summarized it in a recent comment to him:

I’ve noticed your complaints up and down this thread, I’ve also noticed them around the threadiverse for a while and I am beginning to see a pattern. You tend to be aggressively argumentative, denigrate women as a whole/complain about “woke”, refuse to see things from other people’s perspectives, and don’t listen to anyone’s advice. Have you ever heard the phrase “if everyone around you is an asshole, then maybe you’re the asshole”? Perhaps part of the issue is your behavior and attitude.
