the worst kind of 12yo is the one who want to change the world for the better but they're fucking stupid so their well intensions end up serving the bad guys and screwing everybody else. the story of ukrainian NGOs - literally did the dirty job for oligarch and stayed in denial until the stink became biohazard.

The elements of fascism could be construed as a childish/immature perception of reality, where the performance/aesthetics of maturity (particularly as perceived by chauvinistic men) is paramount. The examples listed in this post speak to uniformed (i.e childish) views on power, masculinity, and justice. These topics, among others, are sticking points of every flavor of fascism.

I'm not necessarily saying that this means the american population is immature, but our current fascist regime utilizes these tropes (among other elements of american culture) in their rhetoric, propaganda, and policy decisions to influence the population in pursuit of fascist ends. Seeing fascism as immature/childish certainly has validity, but I think the OP fails to fully capture our current political context with this lens. It would be better to see the state of american politics through the perspective of a failing proto-fascist empire metastasizing into a full fledged fascist regime, informed and shaped by its own reactionary propaganda, of which a large amount appears childish upon first glance.

Everything I don't like is fascism, the more I don't like it the more fascism-er it is
