You see, this is the reckless, dangerous attitude towards understanding the online far right that I was talking about. 4chan is, in fact, not a ground zero for fascism. Hell, its predecessor, Fuck You and Die subforum of SomethingAwful, is also not the ground zero. For a standalone website, that's stormfront in 1996, though we can track it farther back for disparate chatrooms and forums even before SF. SA, to its credit had no explicit Nazi stuff as a rule, but FYAD, up til its deletion by Richard "lowtax" Kyanka as one of his last acts as SA's admin, started getting bolder and bolder with dogwhistles to the point where not even lowtax could avoid confronting doing something about, in his words, "a loving racist shithole with no redeeming qualities whatsoever."
Ah, we've gotten off-topic. 4chan as the ground zero, right. Anyway, it's, like, literally just not true, and this is very easy to verify. I am starting to think that these people are not too serious about studying the far-right on the internet. If they did, they'd know that 4chan has always been a place for embittered nerd boys (that heavily, heavily skew white) to gather and all sorts of bigotries have always been tolerated, yes, but also that stormfront, a website that we always need to be aware of when we talk about these things, only got serious about recruiting on 4chan after moot sold 4chan to 2chan's former operator, wherein the infamous politics board reopened and allowed for stormfront's posters to infiltrate /pol/, and from there, every other board.
The stormfront recruitment, however, also needs to be put into the context of gamergate, a radicalizing event that happened on /vg/, but quickly moved onto 8chan and reddit, becuase moot, still the owner of 4chan for 1 more year at this point, moderated /vg/ and banned the organization of organized harrassment (one of the two good things that moot ever did, the other being closing /pol/ before hiroyuki opened it again), and this follows the trajectory of what I'll talk about here shortly:
Qanon might have gotten its start on 4chan, but the Q research board was on 8chan, following the more committed and radicalized gamergate nazis. I won't even get into how funny it is to do this gnashing of teeth about Qanon when their best effort was the January 6th. Even if Qanon is as scary as these liberals "leftists" believe, most of its worst, socially reactionary, and yes, violent tenants were developed on 8chan's Q research board. While Nazis from stormfront certainly changed the broader culture of 4chan for the worse, and far and away, a lot of those Nazis stuck around, it until wasn't the iberian wedding of the two after hiroyuki's buyout that we could really say that 4chan resembles what we see today.
Once again, these (mostly)-boys that populated 4chan have always been embittered and expressed this in bigotry, both ironic and unironic, there is no denying that. However, we have to keep our eyes on the cultural historical context here. 4chan, like every other site, goes through changes, both in terms of userbase and management. To deny this and transpose the current iteration onto all iterations in backwards perpetuity or even worse, the idea in your heads as the only version that exists, helps no one but people who want you to be less informed. It is a comforting lie to think that 4chan is a singular bad place, and not a place borne out of specific grievance-based nerd culture of the 2000s that interacted with worse places and had the worst of its demographics spun off into multiple worse places. However, believing in this will surely be worse for understanding how the far-right ideas travel through the internet, which only makes you more susceptible to their dogwhistles.
Like, I also give an outsized assessment of 4chan for spreading orientalist notions of what Japan is like for the English-speaking audience, some of which the supposed "progressive" people repeat without batting an eye, because before stormfront, it was 2chan's far-right nerds that, seeing a western gathering of nerds with a format familiar to them, planted the seed of seeing Japan as a reactionary paradise, frozen in time and unable to make progress, a notion that the nascent users of 4chan took back to somethingawful, then to the rest of the 'net as, for better or worse, people from somethingawful became tastemakers on the english-speaking internet.
Even then, I don't place 4chan as this Saṃjiva hell where violence forever spills out without concern for anywhere else on the internet, like some people tend to see, because I saw the migration firsthand and I read people with even more qualification than me write about these things. If you want to confidently speak on how a website has impacted the culture writ large, like any other entities that exist in cultural context, you have to study its history before making an arugment!
All of this isn't even getting into how outside of the United States (and Japan and South Korea and China; basically anywhere else without a parallel far-right net infrastructure), facebook has been the consistent way for the far-right to organize, including facebook hosting the incitement and organization of multiple far-right calls for genocides across the world, with Ethiopia and Myanmar being two big examples.
