I'm sorry, this sort of hysteria and screaming genocide is partially why people discredit the Left even when there are actual, real problems.
Is the treatment of illegal immigrants under Maga awful? Absolutely. But screaming genocide because it's the worst thing you know, well goddamn, now we just sound dumb. This ain't moving us to a place where we can figure things out. (You probably can't have everyone in the world who wants to go to America in America. Conversely, they are still humans and even if they are illegally in the country, sending them to an El Salvadorean prison is heinous.) If we aren't there to make the reasonable case, no one makes it.
It's like how the right complains that Christianity is under attack etc and they are persecuted for it. Is that true? No and it makes them sound insane. Are there actual arenas wherein things are harder or tricky for religious folks? Sure! (If you believe the Pope and feel abortion is murder, pretty hard to reconcile that with funding abortion etc.)
