So the answer to Arundelo's question would be "none of Rand's heroes are that way, while her villains are that way." Wouldn't such a choice by a writer generally indicate disapproval of such a trait? Particularly given Rand's theory of Romatic Art, I'd say that's a certainty in her case.

The question is what happens when some real-world person takes John Galt as a role model.

I have a rather limited sample of Objectivists that I have known sufficiently well to know that they in fact took Rand seriously. 3 people. They all turned out quite well.

What's your data?

I can't detect an actual case being made in your comments, though I think I see a lot of innuendo. Do you think you've made a clear and compelling case? Could you spell it out for me if you think you did?
