I am not arguing authoritarianism or democracy, just pointing out that anybody can believe or say anything they want in a society with free speech.

What is the forcing function that moves voter toward making informed choices, whatever informed may be?

That still implies an uncomfortable level of authoritarianism. Educated by who, about what, how, to what end? Facts and opinions often don't have much to do with each other.

Educated by society, about democratic principles, through any means available, to teach informed decision making. No authority required, except for a commitment to the democratic proces; the rest is up to society itself.
