reddit has harmed its own community standards immeasurably by steadfastly refusing to rein in its most problematic communities, the_donald being one of them. They've only ever dealt with issues when the chorus of negative PR becomes so much that their hand is forced, as what happened with jailbait, fatpeoplehate, and a few others.

The people attracted to those communities don't just stay in them; they spread out and infect the rest of the site as well with 4chan-style shitposting, trolling, and bigotry.
