Research published in Current Biology shows that people with radical beliefs have metacognition problems; they are unaware of their own beliefs, so unable to recognize the errors in their thinking. There's little use arguing with them.

I have a policy of suppressing a smile and changing the subject when religious GOP nuts are holding forth, and often advise others on this forum to do the same.

But tonight I myself became confrontational with my oldest brother, a tall, wealthy, nuclear physicist, who's also religious and a Trumpite.

When he began expressing Conservative views, mocking me when I countered with facts, I tore him a new one, but he laughed and called counter arguments "fake news."

I told him he was living in a white, Protestant, hetero, male privilege bubble..for instance, nobody had ever taken a shot at him for being black, or groped him at work for being a woman.

But I added there was no use talking to him because he never read anything or watched the news, so didn't know anything.
Then I went for a hike with my little rescue dog to cool off. I'm the one who felt angry, but he didn't care at all.

So, I proved the wisdom of my own advice..just ignore religious fanatics, since they lack the metacognition ability to grasp their errors in thinking.
