The cliche is that democracy is horrible and stupid, but it is better than all the alternatives.

Every time you have imposition by the few on the many, even if it starts with the few you agree with imposing the ideas you agree with, there is no mechanism to keep it that way. Indeed, the mechanism for gaining power within a system like that is probably quite different from the mechanism of having the kinds of ideas you agree with.

So what do we do when we have something that sounds good in theory, but sucks in practice? If we are rational we abandon it. Allowing the unwashed masses of fools and hypocrites to pick the policies of their nation by voting on them is a horrible idea. Its just better than forbidding it.
