I can't really get my head around how every well-known internet source - Google, Twitter, Facebook, Wikipedia, Reddit - is so left-wing. I know that they like to defend their biases (when they confess to them, anyway) with Stephen Colbert's "reality has a liberal bias" quote, but right or wrong, there are a lot of people who disagree with leftist politics and even more who disagree with the extreme fringes which seem to dominate the "default" internet. It's even stranger when you consider that the early internet was right-ish libertarian leaning.
