If a list includes Ayn Rand and the title for the list doesn’t start with “[N] Worst [Writers|Artists|Philsophers|Thinkers|Economists|Women] of” then it’s a bad list.
Sometimes, it is that simple: "Rand bad".
But, yes, Rand’s turds do appeal to those poor enough financially that they didn’t receive a rich and broad education and poor enough intellectually that they couldn’t give themselves one.
