I think this is really interesting and and I think it would have been stronger without digressing into current political events. It becomes a self-affirmation - "everyone who agrees with me is clear-eyed rational thinker, everyone who disagrees with me is laboring under from psychological shortcomings."

We all sometimes fail to do a "good job of distinguishing between a threat and someone trying to warn" us. Pretending it only happens to people who disagree with us is just another delusion
