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 I’d make an exception, but it would be a very academic one:
Some teens go through a phase of profound emotional dysfunction. Some of those do the right-libertarian thing without being irredeemably pathologically broken. In most cases though, they stay broken.
