Right-libertarians are all sociopaths. No exceptions.

(It's taken me decades to settle on this opinion—I dislike generalizing about groups of people—but there's nothing tentative about it any more.)

@cstross that wouldn't surprise me at all. There's a theory that the more right-wing someone is, the smaller the "us" in "us and them" is. It's not a huge leap from a small "us" to "me".
