Given how much SJW dangerhairs tend to hate anime and love punk/goth culture along with Antifa more or less getting their start within the 1980's punk rock scene in North America (in Europe, they were around before punk existed) then I'd say punk is the bigger culprit here than anime.
If I had a time machine, I'd go back in time to 1977 and gun down all the members of The Clash, Black Flag, and Crass too. Especially Crass.
The Ramones would be spared and so would Seth Putnam, but Jello Biafra would only be spared if he agreed to never do that "Nazi Punks Fuck Off" song and only stick to spoken word albums
Granted, weebs are god-awful but punk culture is one of the few things that's worse
