@jascha while I agree that it is indeed an overly generalist statement, I don’t think you should dismiss everything someone says after they made a possible mistake.

Physicians often don’t want you to know about metaphysics. Biologists often don’t want you to know about endogenetics. Computer scientists don’t want you to understand quantum computers.

Scientists are people like everyone else, and they too will often deny what you say based on bias or pass you off like a hot potato.
