there was some episode of the animated series–which was about a cornfed pro-america version as there ever was–I don’t even remember the plot arc, but an antagonist was some rogue government agency that was doing the dirt.

anyway, at some point superman and some agents come into verbal conflict. the whole point of superman is that his OP AF, so superman says something they don’t like and one pulls some kind of fancy gun indicating that it can cut through several inches of steel in a second, while menacingly calling Superman an “alien”. it blew my mind as a young person, because saying superman isn’t American is like saying baseball isn’t American, but I had to accept that there would always be pieces of shit like that who viciously seethe and will manufacture any rationale to exclude others… and that “not born here” was an easy, off the rack tool for it.

if I were doing capeshit, I would cram it right up their cram holes. like create satirized but obvious versions of pundits and media owners complaining about immigrants, shoehorn them into the story, and make the entire conflict about how believing strongly in these imaginary lines drawn by the most powerful assholes puts you among the stupidest rubes in the history of the species.

like Terminator: Dark Fate just slightly touched on these themes and showed how efficient, effective, and easily border control resources & infrastructure were for the evil AI’s agenda. it wasn’t even a major part of the overall plot, just maybe 20-30 minutes of “oh shit, of course it would use these tools” against humanity.
