You have a good point about driving people underground, instead of giving them an outlet - but as the article points out,
> Like the mod said in his own words, they are not interested in public policy, they are focused on white nationalist racial discussion. To continue on that course without steering into hate speech is impossible.
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.
