Why are *so many* Libertarians so smug and annoying?

[ingemann]

They only seem so incredible smug and annoying, because they ride on a wave right now. While at this point in history, it's social unacceptable for the extreme left to talk about, who will be against the wall after the revolution, it seem it's mostly acceptable among the Libertarians and their ilk to talk about letting the poor starve to death and violent uprising against the government. Of course at some point that too will be completely unacceptable (of course at that point, it will on the extreme left likely be acceptable about what happens after the revolution again).
