Well, that's irrelevant, as free speech is not about "good ideas winning", but all ideas being able to be heard.
Saying that some are "demagogues" is begging the question, and presumes one side has the good ideas, and the other doesn't.
Which, whether is the case or not, should be irrelevant from the perspective of free speech.
"Free speech for good ideas" is not free speech, it's a dictatorship of people prescribing and controlling which ideas are to be considering good.
