A lot of the racist and islamophobic talking points get exported from the US, then they seem to mull around in Europe for a while, and eventually the US right wing points at what the right is saying there (particularly in the UK) and reimports the rhetoric, often as if it's now solid evidence.

It happened with anti-vax as well. I remember finding it very striking when I started hearing US anti-vaxxers refer to "the jab" in 2020. That's a term we never used in American English.
