This is hilarious to me. I haven't really had much opportunity to interact with them before so just today I got into a discussion about how Americans weren't the most propagandized people in the world because N Korea exists. Apparently NK is a pretty cool place and I just refuse to believe it bc I'm a propagandized American (oh sorry, they say USian for some reason).
Their flair for supporting LatAm anti-american groups has caused them to pick up the LatAm chip on the shoulder that nobody else uses "America" to refer to the whole of North and South America like they do, and instead use it to specifically denote the US.
Oh right, I've seen that before. It's just a culture/language barrier thing, like pretty much everyone who speaks English uses American for the US, but it's different in a lot of Spanish speaking countries. Funny that it also stems from an anti-American place though. Those folks seem exhausting.
It doesn't necessarily stem from an anti-american thing, it just so happens that a lot of anti-americans just so happen to have picked up that particular linguistic quirk.
