The self-proclaimed Objectivists I've met have all given off a creepy vibe. I think it might be due to misinterpreting Rand in precisely the way you described.

They call themselves Winners, imagine themselves as heroic protagonists (far superior to plebs like you) despite never having actually Won anything; it's all society's fault.

They might as well say: "Oh, I was behaving as a good Rationalist, but my opponent was Irrational! It's not my fault!"

Did they say "I'm a winner" in your presence? How did you know what they imagined? That you felt a "creepy vibe" says more about you than them. Where else have you felt this "creepy vibe"? I don't see a lot of extensional facts in your criticisms of Objectivists. I just see that you clearly don't like them.

The Objectivists I have personally known have been fine, decent, fun people. A married couple that went off to be professors at the University of Georgia. I knew the husband better, and played tennis with him while we were both in grad school. Neither of us were very good, but it was exercise.

They invited me over to their house a few times to play bridge and have drinks with some of their other friends, all Objectivist leaning, if not Objectivists. I always had a good time. They never told me they were "Winners". The discussions were lively, honest, and interesting. They gave me quite a pleasant vibe, of honest, rational people who didn't have a lot of time for trying to getting ahead by snearing at other people.
