A symptom of this I often see is that a great many Americans also feel the need to highlight to the entire world around them when something they encounter is Other, or outside of their wheelhouse, and this applies even to the most mundane of things. I have two examples of this:
First, back in 2020, a lost walrus visited the Welsh town of Tenby for many weeks and menaced its lifeboats by sleeping on the slipway. I wrote a lengthy post about this, and included the fact that the good folks of West Wales named the walrus Wally, after the children's book franchise Where's Wally.
I was inundated with Americans reacting with everything from astonishment to derision that the character is not called Waldo outside of America. It was constant. Everything from "Wait you guys call him Wally??? Not Waldo???" all the way to "Are you guys fucking stupid his name is Waldo omg"
Which is very interesting, because Where's Wally is a British franchise. He was called 'Wally' first. His name was translated into over 30 other languages, including Charlie and Jonas, depending on region. Nonetheless, I did not get one single solitary note about the name from anyone else; it was exclusively Americans, unable to keep their amazement to themselves, unable to not highlight and point out that SOMETHING IS DIFFERENT FROM US.
Second, I once wrote a post in which I, a speaker of British English, used the word 'gaol' - the BE spelling of 'jail'. Again, I was flooded with comments, asks, messages, etc from Americans who simply could not fathom why I had done so. Four of them very literally sent me asks that asked why I had done it (I mean this literally - "Why did you spell jail like that?" was word for word one of the asks), so unable were they to work out on their own that spellings differ between dialects. I responded to one, saying that I was baffled by it, and suggesting that maybe the polite thing would be to google these sorts of things for yourself rather than requesting to have your hand held through the process of learning that other places have different words and spellings than you're used to. I said I did understand, but that this was something I myself fetched up against all the time with American media, and had since I was a child - but I simply used context clues to work out meaning, or google when I couldn't, because I get that American English is a different language.
And then two things happened: the first was that a non-trivial number of Americans lost their entire shit at the very suggestion that there was anything at all rude about this (again, I really don't know what answer they wanted to that beyond "Because that's how it's spelled in my language", information readily available with a single google search), and the second was that I was then inundated with non-Americans sharing stories of how they love writing fanfic but they had to start doing it in American English because when they used their own, they would get flooded with comments from Americans trying to 'correct' them, and it just wasn't worth the hassle.
And it's ultimately a 'dominant culture' sickness, I think. When everything is constantly catering to your understandings and cultural expectations, anything outside of it feels Other, and Must Be Commented Upon. I'm Welsh, and I find absolutely any mention of anything Welsh around most English people gets the same reaction; they absolutely have to comment on the Thing They Think Is Weird. Just last week I was discussing a fieldtrip for my students with an English colleague of mine, and I said I was taking them to the Bannau Brycheiniog. He didn't interrupt, to his credit; but he got the stupid grin that I knew meant he was going to comment. He waited until I finished asking for his risk assessment input, and then rather than answering, his first response was "The Bah Bah Bluh Bluh?"
If I'd said an Anglicised or English name, he'd have just continued the conversation. But he didn't recognise the name Bannau Brycheiniog. So We Must All Flag Up That It's Weird.
And that's dialled up to 11 for a great many Americans.
(Though not all, by a long shot. I do want to stress that. In both examples I've given, I had far more Americans who agreed with me than not. But it is a common behaviour, unfortunately.)
