They are ALL democracies, and I'm unaware of a single country on the planet that is a pure democracy. All are representative in some way.
This bizarre "not a democracy" (for the oldest ongoing democracy) is not based in reality at all, but someone read it somewhere and just mindlessly repeats it.
> It's easy to win elections when you promise free healthcare, free education, free childcare,... The average person will vote in their immediate interest and not worry about the big picture
In reality the "average person" votes against their own interest -- both short and long term -- at virtually every turn.
I feel like I've been trolled.
