4chan is infinitely more enjoyable than the majority of social media and forums out there, precisely because of how lax the rules are and because of the lack of perverse incentives for users trying to one-up eachother for internet points. The only real rules are that you can't post anything illegal and that you have to stay vaguely on-topic, and it works great.
Also, /pol/ is not all of 4chan, there's a reason it's called a containment board.
The irony is that even /pol is more "diverse" than the groups commonly requesting content control.
I suspect in intolerant times like this a lot of Jews and black people, which are probably still the prime targets of /pols "hate" go there on holiday just to get away from crazy.
Maybe not too healthy, but very much preferable to another slick corporate or political message about how they will implement racism in the future. At least /pol fails with their racism. Governments and corporations are pretty successful with it.
