When it covers both sides, I do. If you can't tell (and I think it's readily apparent) that the author is in and of himself a generalization. He couldn't BE any more Liberal-Douchy. That's what I find funny. He hits the nail on the heads on some of it, and the rest is just a Liberal parody unto itself. Is it intentional? Doubt it. But, then, that's what makes it even funnier...
