While this is a large part of it, it's not the only thing. Every thread here, and elsewhere, must devolve into gender/race/politics, even if that couldn't be further from the point of the OP. It doesn't even matter what it is that you're trying to talk about, how you want to talk about it, what facet of some media you posted about, etc. It will inevitably turn into those three things, while everyone accuses each other of being from /pol/ and reddit. Every thread has the same outcome, and any attempt to even say something on topic will get ignored or responded to with the same trash.
Moderation is a joke, and the entire site suffers for it. But why would they kick anyone out? Jackie 4chan just wants bodies on the site to click on ads regardless of the quality of the place.
