I've never understood that either, and I've seen such terms used by members of the groups being mocked. Honestly, how are 'nigger' and 'fag' anything but racist and homophobic? It's as though they find such terms funny simply for their 'edgy, taboo factor', rather like Don Imus' and Howard Stern's senses of humour.

It really is like those Ayn Rand worshippers. Some of the snarkers do say that they're Libertarians, but many of them do not, and they will support Obama in one breath and sound like one of Limbaugh's lackeys in the next.
