Of course Rand lovers don’t have a monopoly over freedom of association. That said, doing something that looks antisocial and silly from the outside and then responding to the lightest of scrutiny by explaining that you have to isolate yourself in order to protect yourself categorically from anyone that might criticize you (to quote you: “But, really, what really annoys me about what people like you…”) is… a trope. It’s what every Rand protagonist does because she was not a good writer. It is somehow also the sort of thing that people that read and enjoy her books tend to seek to emulate in real life.
