Ann Rand did, in fact, expect everyone to agree with her on every point. She was an intellectual show off and a bully. You can see her speaking on various old TV shows on youtube. As a writer, she was less dogmatic, but of course, you can't really dialogue with a writer.
In Wolff's The Old School, he speaks of a private boy;'s school, he attended where an industrialist benefactor insisted on bringing Rand up for a chat with the boys in the 1950's. She assaulted the boys, the industrialist and everyone present as "collectivist statists" and left in a huff. The author, who had read and appreciated The Fountainhead was disillusioned with her, as she attacked Hemingway, whom she had never read, because one of his characters was wounded in his manhood in WWI. She said he deserved it.
She came with her own cheerleading squad.
Personally, she was a rather hateful woman who grew into a hateful old crone.
