I know a lot of Trump supporters who are nice people, but I also know a great many that are overt racists. It’s never against me (they make the point they aren’t against “people like me”) but there is always a group they don’t like - other Latin Americans (I’m from Brazil, but they also are usually surprised when they learn that), Middle-Eastern, Indians, and, lately, Chinese (and others, because they can’t tell the difference).
Many Trump supporters specifically, and USians more generally, don't know a lot of things that many people in other countries know; basic general knowledge about the world, including other countries, being a prime example.
For example, I've across some of them who think that the (sole) language of India is "Indian"! :)
There is no language called Indian, dudes. India is both very diverse (regionally and subregionally and fractally), and a melting pot, like the US, and has been that way, for centuries before the US became like that. In both cases, it is due to both being huge, geographically, and due to the invasions in both countries.
I bet they don't know, either, that cuba is pronounced koobaa, or that [1] hermano (brother) is pronounced ermaano, or that jesus is pronounced haysoos, or even that george (jorje) is pronounced horhay :)
I learned that about koobaa from a kooban :) friend in high school, and about horhay from my aunt who went to the US, did her PhD there, and became a univ prof and a US citizen, and about ermaano from google:
wow, that upside down exclamation mark is cool! I wonder whether it has any particular significance, compared to the upside up one ;)
of course that is from an English speaker standpoint, Spanish speakers may well say that it is normal, and they would be right, of course. there are no rules that prescribe what is right or wrong when it comes to language or even culture.
which is part of my overall point.
I think I first saw it long back when I used to read western cowboy novels and comics as a kid.
