The Dunning-Kruger effect explains that the problem isn’t just that they are misinformed; it’s that they are completely unaware that they are misinformed, which creates a double burden.
This applies to both ends of the political spectrum, of course. The question is whether the infected individual naturally lacks the capacity to see outside of their ideology, or whether this blindness is the product of conditioning over time. My guess is the latter.
The same intellectual myopia manifests when the ideology-infected individual is unaware that they are indeed infected. Those stricken with a hardcore partisan ideology simply, literally don't see how similar their behaviors are compared to those they so loathe.

The OP discusses "A Complete Psychological Analysis of
Trump's Support" in general, and the role the
Dunning-Kruger Effect plays in this in particular. The quoted article asserts that Trump is unique on the political landscape, and the explanation for his support has to account for that uniqueness. It sets out to demonstrate that there is a variety of confluent factors, ranging from the benign to the out-and-out vile, explaining the continuing support for Trump.
Mac quotes "Dunning-Kruger Effect", completely forgets about it, and then chooses to ride his shtick - finds "hardcore partisan ideology" on all sides, vigorously dragging the thread off topic.
That's post #6, and it's getting worse, and personal, thereafter.
The place is in need of a clean-up.
