I guess it is about what one finds entertaining, but over here (Finland), I would say that the hate speech sites are just the regular newsmedia discussion areas. Even if they are obligated to moderate, I think the most pissed off, butthurt, whiney, aggressive, etc comments are found there. Media makes news story of something, and invasion of hatemongers spam the comment section of topics.
I think it was entertaining years ago, but how much would I waste time on sites designed for undirected raging & butthurt? Not much.
