They all, to various degrees, are also interested in tearing down the limits to their power over me.
The two most obvious features here are elections (not referenda), and the judicial system. The latter adds an element of “village elders”, while the former makes decision-makers confront hard choices and their consequences.
That’s why direct democracy is considered rather harmful: just look at the clusterfuck that is Brexit for an idea of what happens when people are allowed to make fantasy decisions while disregarding their actual implementation.
As an analogy, consider trial-by-jury (managed by a competent judge) with having all of the locals decide all criminal cases once a month based on what they read in the (disappearing) local paper and on nextdoor. Who would you want to decide the punishment when the neighbor boy accuses you of touching him in funny places?
Brexit wasn't direct democracy; the public vote was a non-binding referendum submitted as an electoral strategum by the elected government, which then quit in favor of a new government of the same psrty, which decided—though in no way legally compelled to—to treat the vote as if it were a binding order in order to pass responsibility off onto someone other than itself.
In an actual direct democracy, the people would vote on the actual policy details, not vague generalizations only if and when it seemed likely to serve the political strategy of the ruling officials.
Brexit is not a failure of direct democracy.
But in any case, in a direct democracy, if enough people want to vote on something, they can, regardless of how stupid it is. That would include Brexit etc.
Otherwise, if it's to survive, it does so by compromise, tradeoffs, bargaining, and leaving many people at least a little unhappy but not enough people unhappy enough to dismantle the system.
Here, Wikipedia has a decently long article on it[0] to get you up to speed.
When you're done reading, maybe you can stop prevaricating in this thread and just state whatever case you're trying to make.
I've noticed people tend to draw the line at "too much democracy" when it starts doing what they don't want it to, and they draw the line of "not enough democracy" when it doesn't do what they want it to do.
That seems like an even mobbier mob than a 51%. At some point, though, you'd figure the numbers alone grant the political fiat to turn the "mob" into the "people". Otherwise, that's one quite "limited" democracy. But, if so, I wonder what the magical ratio is.
Alternatively, they introduce an involatile shared fiction into the public conscious, that justifies their position - such as the divine right of kings, or the sanctity of the feudal contract.
What most of us want when we say we want to live in a democracy is not a true (absolute) democracy, but a limited democracy. We want a democracy within limits. In particular, we don't want 51% to be able to vote to take away the rights (or the lives) of the 49%. In an absolute democracy, they could; in a limited one they cannot.
Populism is, essentially, turning the democracy into mob rule. If you don't have limits, then the mob rules. If you do have limits, populism tries to erode them so that the people can do what they want.
Note also how populism is often associated with authoritarianism. Someone who wants to be the authoritarian persuades the people that he will get them what they want/need, if they just remove those pesky limits to his power. He encourages them to tear down the limits to government power in the name of the people getting what they want - that is, in the name of democracy. But when the people want to reign in the authoritarian's power, they find it's not so easy, because they gave the new power to the authoritarian...
