Can you show me a single time in history when a ruling class simply “ceased to exist” due to a “primarily progressive” populace?

Ruling classes: classes with power, money, capital, do not simply cease to exist. Their power isn’t given up so easily.

Your original premise that only conservative voters protect the ruling class is so demonstrably wrong. Look at at the entirety of the social democratic Europe: who have attained riches from the global south. Look back to FDR voters who cheered internment camps. Look at modern Biden voters who tacitly approve genocide in Gaza. Look to the social democrats who betrayed leftists in Germany. Make no mistake: democrats preserve capitalism.

You have a warped view of our issues as left vs right when they’re actually up vs down: which plays into the hands of big interests like big oil. And the result is that you are pacifying people who would otherwise be doing actual class analysis and have some ounce of revolutionary fervor. Instead, you’re perpetuating the myth that all the evil we experience in our politics is due to baddies on the right who are proud Republicans.

I suspect that as time goes on, while the US and world continue to backside into genocidal fascism, you’ll find yourself confused and aimless, wondering why every tool at your disposal (electoralism, kissing the feet of democrats) isn’t helping to stop Nazis.

You have to read some Marx and understand these are class-based issues as opposed to left v right.
