I dont put much stock in horseshoe theory, but it is fascinating to me that both the furthest left and the alt-right seem to be united in their love for anime.
Not aimed at you but the right leaning side of this particular sentiment is beyond annoying here, and should be banworthy (when it's in a random thread). It just derails discussion in nothing more than a "LOL you like NERDY SHIT" ad hominen attack trying to make someone feel bad for liking something.
Basically, alt-right, as much as everyone loves to pretend, are people. People like different things. They also like cars, meat, guns, using the bathroom, television, video games, the internet, working out, going to school, ect.
All my friends are super into anime and most of the communities I engage with also fall suit, not a single person I know is alt-right. They are all progressive, lgbt, or some other very left side of the spectrum for their country.
