Some North Koreans see Kim Jong Un as a literal deity, because that is what they are indoctrinated to "know."
Some people have smart parents that help them, some people are naturally gifted, some people see the horror capitalism inflicts from an early age at a personal level that overrides the programming, but our nation is captured by the capital market, as its education system.
They probably aren't fixable, but our millions upon millions of willfully ignorant capitalism worshippers voting and advocating directly against their own interests were made, not born that way. They are the default, the ideal laborer, from the owner's perspective, the kind that accepted their lies as self-evident, including hatred for anyone but devout capitalist market worshippers.
Your rank and file Republican voter was just a kid of average intelligence or below, fashioned into a soldier for big capital to maintain the exploitation they themselves are also subject to in perpetuity.
But if that isn't enough, the most important reason to pity the poor ignoramuses is this:
The owners WANT those intelligent and equipped enough with critical thinking and reasoning to hate and fight the caste of ignoramuses they've made. That is a feature not a bug, because so long as the ones that can see this crony capitalist system for what it is hate the ignorant masses that defend it against their own interests, and vice versa, we'll never have the ability to rise up against them. It's yet another layer of control.
By hating the victims of capitalist indoctrination, rather than understanding they are victims too and a painful symptom of the disease that lives in capital markets, you're doing exactly what the owners want. Those with hundreds of millions in exploited capital are our actual enemy, debating/fighting the legions of their lobotomized victims/useful idiots is a sideshow.
Those people are a blight, don't get me wrong, but if there is a solution at all, it's bypassing them and fighting the tiny class of people that created them, easily identifiable by the way, as they love to be on Forbes lists that show off their ego scores.
Almost always, if you want to know who the real problem/perpetrators are, you need only identify who's holding the big bag of loot thanks to the situation. Ho dunk Cletus in the trailer park may have voted for Trump twice, but he is not a beneficiary, just a cultist who isn't bright enough to understand he's a cultist.
