What do you think the next 'justifiable' reason to commit genocide will be?
So far historically it was "they're not Christians", then it was "wrong location" (cause they wanted the land/resources), then it was "they're not the right race", then it was "wrong economic system", and now it's "wrong culture"; what's next do you think?
EDIT: By justifiable I don't mean it's actually justifiable, I mean most people will consider it justifiable.
Invade Mexico to secure the border and fight the cartel, in reality just an excuse to round up everyone who doesn't speak English in a Guantanamo 2.0 right on the border while doing the same on random Mexican schools and bars/markets "owned by the cartel" or some shit.
Next if somehow US goes to war with China you can absolutely expect Asian concentration camps.
Then inevitably I don't see the US surviving climate change without doing the whole "cleaning the cities" first. At first it will be homeless and drug addicts. Then it will be LGBTQ and in the end it will be camps for climate migrants between states e.g Florida.
