So basically an "immoral debate" would be one that's propaganda in disguise? But why would it be inherently immoral to knowingly propagandize a false idea? What if believing a particular false idea leads to behavior that's safer in large scale? For example, you convince everyone that, I don't know, gasoline makes you impotent. Your rhetoric is so good that everyone is convinced, even in the absence of evidence, and people stop driving so much and pollution is reduced.

Is it immoral to use rhetoric to spread false ideas for a good reason?
