As hesitant as i am to say this, i have been a degen weeb since the 90's and it was absolutely more accepted with whites, even though there was still a massive stigma surrounding it. Niggers used to visciously mock weebs by all accounts (from what i have heard from black weebs) and the whole anime-nigger pipeline only really started in the 2010's with the DBZ/fighting game negros being pushed into the limelight and rappers adding DBZ and Naruto lyrics into their gay little songs.
Yet again, as hesitant as i am to also say this.. i am actively involved with various anime/manga/eroge communites mainly based in Japan, and frequently talk to some of the fairly well known artists.. apart from the Japanese which are the main consumers, it's mainly white westerners who are involved in that scene. The anime nigger community isn't as big as you would assume, and they only scratch the surface with well known shounens such as One Piece, DBZ, Naruto, Demon Slayer and AOT. Predominantly DBZ and Naruto though, those two seem to be popular among the negroes for some reason.
I say she's larping because the whole anime girl ethot thing has been a go to for the past 10 years, if you look at what she posts regarding anime it's only surface level shit. I would be surprised if she has even watched Evangelion or Akira tbh. She's basically the Hasan Piker of porn.
