As an adherent of Thelema, I have a certain affection for pop-Nietzscheanism, although I've tasted the real thing, and know it's far better.
But one pop-Nietzschean I can't stand is f'ing Ayn Rand. Hate hate hate her.
That's one of the reasons I can't stand Satanism. Most Satanists basically read Crowley as if he were Rand (or just let Lavey do it for him).
Tyagi, as always, is an exception. Which is one of the reasons I like him.
