Democracy is properly defined as a united gathering of people which collectively has the sovereign right to do all that it has the power to do.
Gist of Idea
Democracy is a legitimate gathering of people who do whatever they can do
Baruch de Spinoza (Tractatus Theologico-Politicus , 16.08)
Representative democracy doesn't fit this definition. What 'unites' the people, and where do they get their sovereign right? If my neighbouring village votes to invade mine, I spurn their pathetic 'sovereign right'.
