What in the world is this supposed to mean? It means that then political spectrum is varied and vast, and that it's lazy and incorrect to simply take this one aspect and call it "leftist". it also means that the US has a ridiculous, caricatured view of "left and "right" that the rest of the world finds by parts both bizarre and laughable. I suspect, based on the fact that you think it's necessary to provide a quick primer on the origin of the terms, that what I'm getting at goes over your head.
