I also went into that book blind. I was in grade 12 and some organization was offering scholarships to people who wrote an essay about the book. I had a twice-daily 45-minute bus ride to fill, so it seemed like an easy win.

Probably not the type of organization to give a scholarship to those who write an essay critical of the work.
Myself, I read it at age 12 and bought its premise at the time. Therefore I mentally categorize Ayn Rand devotees as people with the maturity I had at 12. That's a pretty low bar they're failing to clear.
