Accepting the gist of your arguments, with some reservations regarding the human nature paradox.
As for the Democratic Party, I was deeply immersed in it for years during the “aughts”.
A delegate to state and national nominating conventions, board member of a large Democratic club, a publicly elected Precinct Committeeman, a hard working, ground pounding campaign canvasser of locations near home and occasionally other states, a licensed security provider (“bodyguard”) for Democratic candidates for local, state and in one case - presidential Primary campaigns (before they qualified for S/S protection).
So I know what Democratic Party “mantra” is, which is exactly why I eventually chose to resign from all of that when it became obvious that the Party could not see the forest for the trees.
And stubbornly refused to consider change.
Oh, I continued to donate to certain Democrats & Liberal pols, and am a so called “Super Voter”.
But that’s where it stopped, until 2024.
As a former military person, whose Oath to the Constitution continues - I’m newly Re-dedicated against the authoritarian cabal known as the “Republican Party”.
Gotta be productive now. Have a good weekend!
