I appreciate you snipping out the other questions, but since you want to go into comparing what other evil populations did, let's talk dehumanizing, even though you have already shown you have no clue what it means. Do you really think nazis and all those groups just started by shooting Jews in the streets? No, they de-humanized them. Lots of propaganda and hateful rhetoric, riling up the evil in evil people.
Trump did want to shoot them crossing the border, and had to be talked out of it, but oh his base would love it. I've seen many a Trumpie online think we should just shoot border crossers, and some in person have told me that. What do you think the whole separate the kids from the parents without a care about re-uniting them was about? That's not de-humanizing them? THat's literal permanent psychological torture. And the majority of the Trump party supported it
Or saying most of them are rapists and criminals. Not dehumanizing? What do you think people want to do to horrible criminals and rapists? It's dehumanizing them, it's what horrible leaders do to lead horrible people throughout history, blaming and dehumanizing the other, and then they do horrible things.
Are you normally this clueless? Have you read a history book?
