Edit: I’m not saying anything negative about the female side here, just the male one
On one hand, you have fanfics, kpop Stans, fandoms, Sanrio, etc.
On the other you have literally 4chan, literally reddit, circle jerks about muh superior white music genres like metal, modern rock, and being “cultured” by liking suffering porn with socially conscious hip hop, Roman history, WWII history, military obsession, geopolitics obsession, gamer shit with n-words and Japan stuff, some weird shit with obsessing over your body/facial features to be the perfect Eurocentric ideal, etc.
Also shout-outs to pro incest and pedo anime culture
In the words of a friend who agrees: White men just cannot be trusted to be left alone together on the Internet
They are not femcels, though there is some shared rhetoric. Femcels are the ‘nice guy’ phenomena, but for women. They essentially believe that men only go for ‘sluts’ (who are almost always described in terms of blackness), and that all the ‘good men’ are already married. That being said, there is a distinct hint more at misogyny than misandry (because, you know, everything gets processed through the overarching lens of patriarchy).
My point isn"t that patriarchy doesn’t exist, it’s that women online will do equally fucked things as men, but again, it is through the lens of patriarchy and white supremacy.
