This subthread is off of devmunchies comment about Reddit and Twitter, and the OP is about 4chan. All of these forums are global.

My point is that American-style conservatism may represent half of Americans, but it's overwhelmed in other developed countries (which, taken together, are larger in population). So much so that I would argue that in the global context, American conservatism is small enough and far enough to one side of the debate that it's accurate to call it an extreme.
