Liberals are intellectuals: Liberals portray themselves as brilliant intellectuals who are so much smarter than the riff-raff out there in flyover country. Meanwhile, back in the real world, they run presidential campaigns based on "hope" and "change" and the intellectual roots of their philosophy could be explained by a caveman. Abortion good! People who want to stop abortions bad, bad, bad! Gay marriage good! People who want to protect marriage bad, bad, bad. It doesn't matter whether it's a college professor, a rocket scientist, or Barack Obama -- they all turn into cousin Cletus, the mountain simpleton who lives out by the hog pen, when you try to get them to explain why they believe what they believe.
Liberals are tolerant: Liberals are extremely tolerant -- of people who agree with them or of foreigners who hate America. Everybody else? Not so much. If you happen to say, try to give a conservative speech on a college campus, say that you believe marriage should be between a man and a woman after you're asked about it in a beauty pageant, or believe science has led you to draw a different conclusion than liberals have in regard to global warming, you're not going to see much tolerance on display. In other words, the liberal idea of tolerance is, "I agree with what you say, I'll defend to the death your right to say it -- and the rest of you need to be quiet."
