Yeah, I've noticed the same thing. There seems to be about 1 "Libertarians are basically Democrats, and even if they aren't, they can't win" thread every day or so.
Flak, target. 'Nuff said.
They also keep bringing up the argument that the (big-government social) issues where libertarians disagree with social conservatives are less important than the (small-government economic) issues where libertarians and conservatives are on the same page.
Well, if the differences are so darned small and insignificant, and the resultant splitting of the vote is so terribly important, why don't conservatives just concede those points and end the infighting?
