U.S. news专门发了一篇文章解释川普抹黑移民吃宠物的背后逻辑，和当年排华法案一样的，当时也说华人吃猫狗。最主要的目的就是渲染这些人和我们不一样，是野蛮人。其实和希特勒和日本人搞种族屠杀一样的宣传，就是挑动一般人对这些人的仇恨，不再把那些人当人看。

所以说川普和JD之流用心很险恶。

NEW YORK (AP) — It's a practice that's about as American as apple pie — accusing immigrant and minority communities of engaging in bizarre or disgusting behaviors when it comes to what and how they eat and drink, a kind of shorthand for saying they don't belong.

The latest iteration came at Tuesday's presidential debate, when former President Donald Trump spotlighted a false online tempest around the Haitian immigrant community of Springfield, Ohio. He repeated the groundless claim previously spread by his running mate, JD Vance, that the immigrants were stealing dogs and cats, the precious pets belonging to their American neighbors, and eating them. The furor got enough attention that officials had to step in to refute it, saying there was no credible evidence of any such thing.

But while it might be enough to turn your stomach, such food-based accusations are not new. Far from it.

Food-related scorn and insults were hurled at immigrant Chinese communities on the West Coast in the late 1800s as they started coming to the United States in larger numbers, and in later decades spread to other Asian and Pacific Islander communities like Thai or Vietnamese. As recently as last year, a Thai restaurant in California was hit with the stereotype, which caused such an outpouring of undeserved vitriol that the owner had to close and move to another location. 

Behind it is the idea that “you’re engaging in something that is not just a matter of taste, but a violation of what it is to be human,” says Paul Freedman, a professor of history at Yale University. By tarring Chinese immigrants as those who would eat things Americans would refuse to, it made them the “other.”
