That’s my take, at least. Jus Soli was implemented in the USA because Jus Sanguinis was going to be the racists’ next tool to shit on Blacks, who were seen as animals to be used up and then discarded. We did a shit job of stopping this with Reconstruction, so here we are. We’ll need to take the gloves off for these people, and punch them in the face (figuratively at least) until they get the idea that it’s not cool to treat other people like shit.
