It doesn't even describe /pol/. This is what 4chan thinks of /pol/ but when you actually go there there is a pluriformmity of opinions and it's indeed mostly just about current events.

The biggest good thing that came out of 4chan and 8chan to me is that it made me extremely weary to ever trust second-hand reports about some place and made me better at identifying reports that read like “This person dislikes this place, never visited it, and just reasons together what it's like.”. It also made me try Tumblr. I heard terrible things about it how it was filled with “social justice warriors” and stuff and unsurprisingly, when actually trying it it was nothing like that and just a fairly chill place where people mostly blog about fiction and pornography and share their thoughts. Even when ignoring the filter and logging out and going to what is trending, almost no content is political.

I remember when 8chan went down and all the news reports and forum posts basically said it was basically Stormfront but I was there at the time and it was nothing like that. People just posted cat memes, talked about fiction, talked about life and dating and stuff. One had to dig on very specific boards to find that kind of content.

People talk a lot about “places”, online or offline or even fiction that they clearly have no firsthand experience with, and just reason together about what it's like. They just “expect it to be like that” based on some image they create in their head, or some cherry picked examples they've seen and start to treat it like fact. It's especially weird when it's about something they clearly don't like, some kind of book or television series of which, despite clearly disliking it, they can supposedly tell you exactly what it's like... well, they've never seen it, they just reasoned it together in their head based on some things they read about it and their own expectations.

I frequent 4chan a lot; it's nothing like this description indeed. I don't frequent /pol/ because I found the discussions to be completely empty but I tried it and it was nothing like that. Even within 4chan I read all sorts of things about other boards that are just not true when actually visiting them. /pol/ isn't a far right echo chamber, /r9k/ isn't full of lonely incels, /lgbt/ isn't some social justice warrior hub despite what one might read about those places on other boards.
