[Confusion]

Allowing yourself to be dragged into the same argument over and over again, because some people are just not listening (creationism, flat earthers, moon hoax believers, ...) is a waste of time. Publicly reminding the readers about the majority view on the situation and then letting the argument go is fine as a response.

(And yes, the majority view is that Rand is not worthy of any special attention as either a philosopher, political theorist, economist or author. Not more worthy than any other random member of those groups of people.)
