Unless they are literally calling for people to take action and kill/harass/otherwise harm people I see no reason to "censor" them. From what I've seen, most of that subreddit is hating on other races(which definitely is hate speech) but not calling any real action. I also don't consider calling for legitimate political action to be worthy of "censorship" either, only going outside the political system to directly harm.
