Take the Haitian migrants in Ohio that are currently the victims of intentional blood libel. As an aside, identifying, villifying and demonizing an out-group like this, particularly to intentionally incite violence against them, is a key aspect of fascism.
The objective falsehood here is that they're "illegal immigrants". They're not. They're Temporary Protected Status ("TPS") holders. It is 100% legal and moral to seek asylum.
And then we proceed to the myth of "the center", much like the myth of the "swing voter". What the US has politically is a choice between the far-right and the center-right who have completely capitulated to far-right messaging on immigration.
Every aspect of far-right anti-immigrant messaging is verifiably and objectively false. The latest lie is "they're eating the cats" [1] but there are so many more. The "migrant crime" hysteria is blood libel [2].
