It isn't any more or any less popular than it has always been. The same goes for stuff like racists, paleo-conservatives, people who read Ayn Rand, overt nazis and other amusing creatures. Our media diet has changed substantially, and now any random idiot with a wildly improbable theory can share it with the world with no effort. Populist stuff that seems to make sense on the surface always has the upper hand in an unmoderated debate.
