I'm thinking things like flagpoles in the yard.
Like you waste however much money and resources to keep your non-native grass around and they drop in a 60 foot pole into it to be able to fly an American flag and flag for whatever shitty college you went to.
What other things are there?
The shitty culture they export to other countries. In Argentina the TV would play Am*rican movies, like those insanely SHITTY christmas movies with the (super) white family and shit like that, or the ones about talking dogs (Bud?) like GET THAT SHIT OFF THE AIR FFS
Their shitty sense of patriotism is insanely annoying, like yeah you live in the richest country that ever existed but oh that country gives ZERO FUCKS about you, idiot. All the riches in the world and you couldn't tackle a fucking pandemic (and make it harder for the rest of us to combat it as well) because AT LEAST THIS ISN'T SOCIALISM BROTHER, SOCIALISM FAILED AMERICA #1
