Democracy is a primitive state of mind, or rather mindlessness, giving "power to the populace" from greek. By definition if there was a developed alien species on Mars, democracy would brand it as non-democratic automatically and wage a full-scale war against it till total extinction of one of the unlucky sides.
You forgot about our democracy, dude? Shave that all off immediately! And no cats allowed!
A form of government where citizens vote directly on laws or elect representatives to make laws for them. It, in fact, DOES work, but people are dumb and vote for the wrong people.
