Yup...I recently began reading Atlas Shrugged, and naturally I became interested in the author.
Seems she was exactly as you described.
She was vehemently anti-religious. I find it interesting she mentions evil but not a thing about being Holy.
She was against the U.S. entering both world wars.
There are some interviews with her on YOUTUBE. One is from Phil Donahue’s show in the lat 1970s, just a few months before Ayn Rand died. She had lost her husband and was still mourning him...but she held steadfast, at least publicly, to her atheism.
Another recommendation is the film “The Passion of Ayn Rand”, which is a SHOWTIME cable show movie about her. Some of it certainly is fictional, but she did have an affair with a subordinate and it messed up his marriage. The woman who plays her is Helen Mirren, the lady who won an oscar last year for her portrayal in “The Queen”. Mirren does a great job looking and sounding like Rand.
For what it is worth.
