It’s funny. People I know who are religious. They may have a head full of scripture but dogmatism isn’t as ubiquitous as you might think. And often behind that scriptural thinking is a proper humility. An understanding that these eyes and this brain are just a speck. A dot of illumination in a vast night. Fine modern scientific and/or theological theories notwithstanding.
The popular arrogance, otoh, is childish. Smug certainty that you have truth in hand. I find that hard to swallow.
Drugs and meditation are the best cure for it as far as I can tell.
