Should conspiracy theories be outlawed?

I totally reject the premise that conspiracy theories, as such, should be banned. I am not inclined to give conspiracy theories the light of day - I see such theories as popular among elements of both "left" and "right" that do not understand the interconnection of ideas. Conspiracy theories are admittedly often highly destructive, but the solution there is counterspeech, not censorship. Those who think that the government can ban conspiracy theories without such a move entailing a reign of censorship that goes out of control are, I submit, simply not in touch with reality.
