I don't know of many Libertarians who are Randroids. They are much more of a tiny minority than this description would suggest.
True, because Rand loathed libertarians, calling them "right-wing hippies", and "hippies" were way down there with Kant as far as Rand was concerned. Her main beef was that, although libertarians shared her political and economic views, many of them didn't reach those views in what she considered to be a philosophically sound manner. She also believed that far more people had to be educated as to the benefits of a free society before there was any point to having something like a Libertarian Party. Although I agree with most of her views, I think she was out to lunch on these points. However, saying so would be heresy to a Randroid, and so most of them are, in fact, Republicans.
