I see a lot of people on Lemmy recently claiming to be left but also trying to tell me how democracies are bad. -_-

Probably the case, although it's important not to dismiss people for criticizing liberal democracy - the system that has repeatedly put us in the mess we're in now. There are plenty of issues which are wildly popular regardless of political alignment but which liberal democracy fails to deliver, so to consider it a democracy at all, simply because most people get voting rights to pick representatives, is very debatable.

There are plenty of other forms of democracy, many which have been successfully run in communities of hundreds of thousands of people (consider Zapatistas, Cheran, and more).
