Democracy - Rule by the majority. People keep saying that this or that thing is democratic/undemocratic, so the only way to make the word make sense again is to give it its original, classical meaning.

A bunch of words that are constantly thrown around that no one seems to want to define:
Fairness, equality, social justice, freedom
