People here seem to be confusing a lot of things that aren't actually the same.
Including:
-Neo-Nazis and far-right racist conspiracy theorists. Entirely wicked. Few actual followers.
-Internet anti-PC sentiment. Extremely widespread. Probably includes most young American males, and many globally. Come from right, left, and center.
-4-Chan memers and pot-stirrers who spread chaos for its own sake. No actual ideology. Usually 12, and prone to horrific acts of mild internet terrorism (hackings and harrassment).
-Traditional conservatism, including critical attitudes towards liberal solutions to racial and economic problems. National Review, Thomas Sowell types. Tend to be anti-Trump.
-Rightwing opportunist provocateurs who'll say anything for attention. Anne Coulter, Milo Yiannopoulos. This is the category Trump himself probably best belongs too. Ideology is fuzzy, but loud, populist, and protectionist. Almost always completely fact-free.
