WHY LIBERALS hate Christmas:

[I]t is not just a moral distinction, though there is that, that drives liberal disdain — it is a fierce desire to maintain a social distinction wherein liberals believe themselves to be intellectually and culturally superior to conservatives. The central appeal of liberalism is the sense of superiority it confers on its followers, no matter how hollow its basis. The appeal of liberalism is to know, indisputably and at every moment of one's life, that you, as a liberal, are better than those mindless ordinary persons that you grew up with.

They're not nearly as 'superior' as they think they are. It's why their bubble is so dense.
