The term “blood poisoning” was used by Hitler in his manifesto “Mein Kampf,” in which he criticized immigration and the mixing of races. “All great cultures of the past perished only because the originally creative race died out from blood poisoning,” Hitler wrote.

Vs:

“They let — I think the real number is 15, 16 million people into our country. When they do that, we got a lot of work to do. They’re poisoning the blood of our country,” Trump told the crowd at a rally in New Hampshire. “That’s what they’ve done. They poison mental institutions and prisons all over the world, not just in South America, not just to three or four countries that we think about, but all over the world. They’re coming into our country from Africa, from Asia, all over the world.”

Trump then repeated the use of “poisoning” in a post on his social media website Truth Social, saying overnight in an all-caps post, that “illegal immigration is poisoning the blood of our nation. They’re coming from prisons, from mental institutions — from all over the world.”

These are literally completely dissimilar apart from the shared use of the term "blood poisoning", which would be a translation from a german term for Mein Kampf surely?

I'm not defending either here, but "xyz is hitler/nazi" is literally said by everyone
