To be fair to Peart, he grew up too.
Q: You were interested in the writings of Ayn Rand decades ago. Do her words still speak to you?
A: Oh, no. That was 40 years ago.
Peart was, what, 23 when he wrote 2112? I had NFI about anything when I was 23 either, but fortunately nothing I wrote then ended up in millions of teenage bedrooms.
