If you're speaking a different language, using a different word is fine. But if you presume to claim to be speaking "English", then you should use the word they use in England.

I claim to speak American English. I don’t recognize any dialect of English, including my own, as the primary one that all others have to follow, because English is a pluricentric language. I’ll never tell someone from England, Ireland, Australia, India, Zimbabwe etc. that their version of English is wrong, and they shouldn’t tell me that mine is either.

This phenomenon isn’t unique to English, by the way. Every language spoken in more than one country (AFAIK) has some words that vary between countries.

Your argument is a bit ridiculous IMO, it’s like saying neovim should merge every patch that gets merged to vim.

And yet you don't know that the term soccer comes from association football and was coined by the English

I'm aware, I just don't consider it relevant.

Oh you're aware you just are choosing to discard relevant information in order to maintain your high ground ? Oh ok got it. Real rationalist over here

I'm choosing to discard it precisely because it isn't relevant, as I said. When and where a word was coined implies nothing about what languages it is and isn't a part of today.

Indeed, but “soccer” is part of American English today. Why should we stop using a word just because people in a different country stopped using it? Is your argument really that we should speak identically to people in England, because the language happens to be called “English” ?

I think you should either conform to English English, or treat American as a first-class language of its own (and e.g. start offering translated websites).
