It's all well and good to use the word 'democracy' in a casual way, but if you're going to write a long article about it, at least define what you mean. Democracy (strictly defined) between two wolves and a sheep is much different than democracy between 150,000,000 million wolves who are going to have to manage without murder and robbery.
A popular vote can only work where divisions are minimal. That is, where it isn't "wolf vs. sheep" or "lord vs. peasant" or "taxpayer vs. tax-eater", etc, etc. There are lots of ways to divide people, and it was only for a brief period, in a few countries, in the past few centuries when such divisions didn't cause authoritarianism.
