Why Left-Wing Bloggers Frequently Use Foul Language

Gateway Pundit is discussing the fact that left-wing bloggers are far more likely to use foul language than right-wing bloggers (according to one estimate, by a factor of 18). I suspect it's for the purpose of ensuring they aren't quoted by the right wing.

There is the alternative theory that they regard foul language as part of an exorcism ritual. Say a vulgar word for a body part or a biological function and conservatives will melt, just like the Wicked Witch of the West.
