It's not just cultural conservatives who do it. I'm going for a Geography and History BA, and the students of every other faculty seem to be in a civil war with us for our "poor choice" and "useless degree." At least we devote our studies to ideas, not numbers. But I guess that's a conversation for another day!
Yeah I can't stand when math-types who don't know too much about politics/history try to say their somehow technically "smarter" because they know math instead. They think they know everything about the universe but when you ask them basic political strategy or history you get a blank state coupled with a dismissal of those subjects in general as being "not important". It's basically a way they try to get out of admitting that someone else is smart too.
