Historically, democracy only allowed free males who were land owners to vote. A minority.
In the last few generations the wealthy have come up with clever ideas to hold onto power while expanding the vote to the majority.
So, I think Democracy is defined by periodically changing some of the government by the voting of some people. And the votes must be counted in front of witnesses.
This is my definition of democracy only; and not me arguing for it, personally I don’t think it works well enough
I think this is my favorite theory
