Without getting too off-topic, I’d argue that the GOP has always been more flexible towards embracing ideological extremism than the Democratic Party has, and this trend has existed since Barry Goldwater at least.
But back to SA culture and its innumerable offshoots and bastards: even if Chapo has comparatively less actual political influence than say Q did (someone posting on a 4chan offshoot), the dirtbag left subculture the podcast spawned is still of internet historical value, in the same way Anonynous (a 4chan hacker collective) is historically significant despite Anon having been dismantled by the security state since the mid-2010s.
Oh, and on that note- perhaps that means 4chan had some influence on the Occupy movement, not as a prime mover but certainly one of the groups participating in it. And while Occupy is long gone, it had its important moment, once.
On the flipside, later on 4chan was one of the major staging grounds for Gamergate.
At some point 4chan’s actions are its members’ own with no connection to SA, but without SA, there would be no 4chan, and the people who acted within it would’ve been redistributed elsewhere.
The hand of Lowtax moves through history like a dumb idiot god, but it does move.
