You're interpreting "just as good" to mean "has equal political power", which is very obviously not what Asimov meant. But even if we take that interpretation, you're still wrong: ignorance has much more political power than truth and knowledge do, because it's not bound by the same rules. Truth is handicapped in the political game by having to, you know, be true. Lies and ignorance have no such handicap, so they're much stronger.

> Asimov rhetorically chose to label one side of an issue as "ignorant" and the other side as having "knowledge"

This is not "rhetorical" -- they are not mere "labels" -- and in calling them that you're perpetuating the exact problem he's describing. RFK Jr.'s position is ignorant, false, stupid, inconsistent, dangerous, idiotic, etc. etc. These are not just labels.
