A: Dictators dress in full military regalia, as if they are on the brink of war. Democractic leaders dress like they are about to enter a very important job interview.
Dictatorships do not allow dissent of any kind. Democracies champion free speech, as long as it does not upset anyone, or hurt someone's feelings, or has anything to do with sex.
Democracies pretend to give power to the average person, even though they are controlled by a select group of very wealthy individuals. Dictatorships don't bother with all the lies.
