It’s true. In my day it was reading “Truly Tasteless Jokes” book and stuff. Boys think it’s mature to be against relationships, mock girls but it’s an extension of “girls are icky” – and verbal fantasies of dominating over women are littered throughout.
It was pathetic to me when I was a kid and it still is. I see it among my nephew’s generations memes and jokes too. Same bad jokes, different formats (memes)– nowadays it’s mixed with perverse hentai fantasy material too but fundamentally the same kind of tasteless adolescent fantasy humor that thankfully most men grow out of.
That said, there is the incels – the men who believe that they deserve a beautiful woman as a birthright and feel that they are personally denied and therefore hate all women as a consequence.
That is something I’d never seen before in my life and they can get very dangerous.
