Earlier this week I chatted online, briefly, with a family member who is an avid Trump supporter. As I raised my objections to various Trump policies he blithely dismissed all of my objections, and I realized, with a shock, that like so many Trump supporters, he doesn't object to anything that doesn't affect him directly. This family member, who is in his 50's, is not a narcissist but he's completely egocentric. This is a developmental stage he should have grown out of at about age 7, but for some reason he didn't. He hasn't had a traumatic brain injury (which might explain it) but for whatever reason, his cognitive development is stuck at a preoperational stage. I wonder if this isn't the case for a lot of Trump's avid supporters?
