Yeah, there used to be a lot of really arrogant know-it-all 16-, 17-, and 18- year-olds who thought they had ALL the philosophical answers wrapped into a neat little package because they read Ayn Rand. I remember when they would smugly recite crap like "A equals A" as if it was something incredibly profound. Oh, and Ayn Rand could NEVER be wrong in their view.
I don't see too much of those young objectivist types anymore. Probably because youngsters nowadays prefer video games to reading. Also, there was a lot of falling away from Rand because of that Nathaniel Branden affair.
