I don't know why you're getting downvoted. Discovered that subreddit through r/ImGoingToHellForThis which is becoming more and more a racist subreddit. I asked there the same question and learned that American put freedom of speech before hate speech and racism (which is not the case in many other countries, France for example).
This is why you have the Tea party and other jokes in the US.
Reddit is following a clear "US" guiderule which is "whatever goes".
Not in the US as far as I know though and that's usually what Reddit takes as baseline. Though I think a case could be made banning them for vote brigading but that might create quite some drama considering the 2 big brigading subs (if you discount positive brigading of /r/bestof and /r/defaultgems) SRS and /r/guns are politically sensitive.
As opposed to "sarcastic" hate speech, like a joke you might hear on Tosh.0. These people really do believe the things they say, and they are intent on spreading their vitriol as far as they can.
I'm not sure what point you were trying to make, though. Unless you really didn't understand what I meant?
