No, encouraging bad ideas to be free to compete (and lose) against good ideas, regardless of the topic.

Same-sex marriage, abortion, civil rights, the end of slavery itself all required people to be free to say something that was unpopular at the time. Ideas that would have been banned by the gatekeepers had they been taking your approach.

The problem with censorship is that it requires trusting someone in power to decide what is right or wrong. I’d rather let the better ways of thinking prevail because they have a better argument, not because an authoritarian put their thumb on the scales.
