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
well i can promise you women have much more varied interests than Taylor Swift and youtube makeup drama hahah. no hard feelings but that view feels a little two-dimensional, maybe it's not the women around you but the interactions you're having with them giving you that impression?
