Democracy also means allowing the people to form and discuss their ideas, on their own terms, whether sane or stupid. Not because that's necessarily best, but because that's democracy - authority belongs to the people not to their government.

The responsibility to lead and guide people's ideas, in a democracy, does not lie in the strict control of government, it lies elsewhere. Where that elsewhere is, of course, everyone will argue differently. But not, I think, in governmental control.
