Yes, but because other forums tolerate extreme opinions on other subjects, people who hold them don't have a particularly burning desire to congregate there.
I don't think anyone's been banned here for liking systemd, or for expressing their support for Israel, but they will be for calls to genocide the Middle East.

If your impression of 4chan as a whole is just /pol/. 4chan as a whole is much more ideologically diverse than reddit due largely to the site's format and lack of censorship, but if you're an outsider to 4chan's (often outlandish and intentionally offensive) cultural norms you're just going to think it's a nazi site. Mainstream media has tried and failed to understand it for decades now.

Yes... because even after decades of industry-wide integration with the web and a generation of people working in media who have grown up with it, somehow they still can't grasp the true nature of this one forum full of shitposting edgelords.
You're actually on point even though you're being sarcastic. Communities aren't hiveminds, and the edgiest members of a group don't constitute the whole picture. Upvotes and downvotes definitely work to make communities act more like them, however.

I don't think people not participating are missing much.
