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
I feel like calling fanfics consumerism ignores the very weird and subversive aspects of fanfiction that can manifest. Obviously doesn't always but that combined with the "this is what the female side is" smacks a little too much of the "women are such stupid consumerists XD" mindset people use to shit on "pumpkin spice girls" or just women who buy a thing. I doubt you intended that and I don't blame you but I hope you'll consider it in the future
media/art consumerism is way more likely to be cool than lots of other forms of consumerism imo
valid
