That's the thing about reddit - it's so big that you can find whatever you want. Whether you want polite discussion about woodworking, erotic fan-fiction, or examples of horrible racism and misogyny so you can write an article for HuffPoabout how horrible Reddit is, you will find what you're looking for.
But I'm pretty sure that was true of the internet before Reddit came along, too. And I don't see how combining all of those discussion groups under the same domain made the world any worse than back when they were three separate message boards.
