It's a challenge.

Southern is still a complex (and, for me, thoroughly unlikable) person with odious views, but it's an interesting journey if for no other reason than you can see just how powerful a force tribalism is in human psychology; how it lets people get right up to the point of dealing with the incongruity of their tribe versus their safety/well-being/reality.

The other place I saw this is in watching the flat-Earther documentary Behind the Curve: there's moments in it when you can see people get within a hair's breath of rationalization, but get held back not by stupidity, or ignorance, but tribalism.

We make a big mistake in thinking that the reason people are the way they are because of ignorance or stupidity. That's not it; they are the way they are because human tribalism has millions of years of success behind it. Up until, oh, the last hundred years or so, ostracism meant real death, so our monkey brains, though millions of years of selection, developed group cohesion and social strategies to help us stay within our in-group. Unfortunately, in the last century or so, that tribal instinct is proving maladaptive.

It's a little like how we're evolved to process sugar, which has hundreds of millions of positive evolutionary enforcement, only to fail at the outside-context problem that is McDonalds & Coca Cola.
