I've heard it called "US Defaultism" where most Americans online seem to assume that everyone they interact with is from their country and all US news is considered significant even when it really isn't.
To be fair, the US has the largest number of English-speakers of any country in the world. As a first language, it has five times as many native English speakers as second place (the UK). It also has one of the highest Internet penetration rates in the world, meaning most of those English-speakers are also Internet users.
The US is a single country that is three-quarters the population of the entire European Union, and nearly all of its inhabitants speak English and use the Internet. So yes, if you pick a random user on an English social media page, odds are very good that person is an American. If you were to guess any random English-speaking Internet user's nationality, "American" is the best possible guess. But go on a Spanish language forum or a French language forum and nobody will assume you're American.
Consequently, Americans generate the majority or large plurality of English-language Internet content.
Edit: Please stop replying with "English is a lingua franca for non-native English speakers". I never made the claim that someone who uses English on the Internet is likely a native English speaker. I am claiming the converse—that people who natively speak English are likely to use English on the Internet.
Tbf it seemed to make more sense for the likes of Reddit, Facebook, etc. Similarly if I go to a Chinese forum I would not assume that everyone there was from the USA.
There are tons of tankie subs where you can masturbate to false expectations of the planet and openly hate people who you've never met before, check it out!
I wonder if a news community with a "no mentioning the US" rule would work. Not out of any hate, just as something arbitrary like "don't use the letter E".
I hear you and am guilty of it myself. I feel like it's due to the anonymous nature of the internet. I think everyone immediately falls into the category of "peer" before putting a touch more thought into who the actual person (bot/ai) is that wrote the reply. Add that to the fact that most Americans see themselves (as a country) as the king of the world.
Maybe you can try typing with an accent, but I think that'd probably just be seen as a racist American.
Aren't the majority of English speakers from the US?
EDIT: The USA has 3x the population of the UK and Australia combined and the USA appears to be the home of approx 60% of native English speakers. However there are billions of speakers if you include it as a 2nd language. Which Americans don't speak 2nd languages so we obviously don't count that.
As someone outside the U.S., what is your default persona for anonymous/pseudonymous users until you know more about them? Just curious. Like, if you don't have any information about them, do you read the words in the voice of a person just like you?
The US has more allocated IPv4 addresses and more users per allocated IPv4 address than any other country, by wide margins - and IPv6 adoption is not that widespread yet. It is entirely rational to assume that an English-speaking person on the Internet is from the US, given no other information.
