That very well may be all this is, I wasn't alive for the last famous president. I suppose folks feelings about him do feel similar to the other types of celebrity infatuation. I've never really understood the way people relate to famous people, I wonder if it is escapism, an inhuman place to project the idealized good or evil they imagine exists but that they never find in people who they actually know.
Preaching to the choir here. I'm that nerd who could go off on all the themes, dyanmics, and philosophies of The Matrix, and then 15 years later hear "Keaneu Reeves as John Wick" and have a blank face. I've never been particularly good at naming celebrities.
But I'd be unsurprised if I was ever diagnosed as neurodivergent, and apparently people find other people's lives engaging or even "relatable". Not that I never had my share of famous people I liked hearing about. It's just that I more resonate with their actions and works than their day-to-day lives.
