one of the craziest things about all the racism is that much of it is trolling from non-racist or not normally racist people looking to get a rise out of people. I see the same thing on YouTube and Reddit all of these troll parody accounts created by ant-social 20-somethings in an attempt to get a reaction or "shock" people.

Reddit can be a great place. Subs like /r/webdev and many, many others are very informative and a great way to meet people. I don't think I've ever seen any kind of racism / hate on the subs I frequent because none of them are main line.
