Democracy is about means, not ends. If we all agreed on the ends (such as whether to build a wall along the Mexican border) there’d be no need for democracy.
But of course we don’t agree, which is why the means by which we resolve our differences are so important. Those means include a constitution, a system of government based on the rule of law, and an independent judiciary.
A dictatorship, by contrast, is only about ends. Those ends are the goals of the dictator – at a minimum, preserving and accumulating personal power. To achieve those ends, a dictator will use any means necessary.

“Never argue with a fool, onlookers may not be able to tell the difference.”
