It is the (radical) left's belief that they can redesign society based on their intellectualism. It would make sense that "intellectuals" (or, people who think that they're smarter than what they are) follow this ideal.
It comes as no surprise to me that the left tend to make arguments based on "intellectualism", while the right's arguments are more philosophical.
Of course, I'm making sweeping statements, here, but you get what I mean.
