I think you are overstating the “Far-Right” activity level. The rhetoric is no different than the rhetoric of the Far-Left during the Bush administration(s). No matter what, no one should advocate violence. I haven’t heard anyone on CAF advocate violence, but I have been disturbed by those who seem to excuse the Tiller murder (even though they clearly state that they don’t approve of the killing of abortionists).
Anyway, some nut-cases, like the one from this thread, are difficult to place as Left or Right. They are just plain un-hinged.
I just notice that you have a penchant for trying to tie any extremist to the Republican Party, as if all conservatives are complicit in such activity.
