In the English speaking world, there are over 328 million Americans who use the term to refer to American football, 37 million Canadians who typically mean either American or Canadian football, and 25 million Aussies who use the word to refer to Australian Football. Brits are a minority of native English speakers.
But I'm not going to say English people should start calling it soccer so I don't get confused. Let everyone speak their native language; there's nothing wrong with it!
Ultimately, the word “soccer” is of English origin, broadly understood in England, and refers exclusively to association football. In any international context, the word “football” is ambiguous at best, and it’s chauvinistic for anyone to insist that the term must exclusively apply to their own country’s version of the game.
I think "soccer" is an Americanism as well.
It isn't. It was originally Oxford slang derived from "association football":
> The rules of association football were codified in the United Kingdom by the Football Association in 1863, and the name association football was coined in the UK to distinguish the game from the other versions of football played at the time, in particular rugby football. The word soccer is an abbreviation of association (from assoc.) and first appeared in English private schools and universities in the 1880s (sometimes using the variant spelling "socker").[1][2][3][4] The word is sometimes credited to Charles Wreford-Brown, an Oxford University student said to have been fond of shortened forms such as brekkers for breakfast and rugger for rugby football (see Oxford -er). Clive Toye noted "they took the third, fourth and fifth letters of Association and called it SOCcer."

> For nearly a hundred years after it was coined, soccer was an accepted and uncontroversial alternative in Britain to football, often in colloquial and juvenile contexts, but was also widely used in formal speech and in writing about the game.[6] "Soccer" was a term used by the upper class whereas the working and middle class preferred the word "football"; as the upper class lost influence in British society from the 1960s on, "football" supplanted "soccer" as the most commonly used and accepted word. There is evidence that the use of soccer is declining in Britain and is now considered there as an American English term.[6]

In other words, even in England, the word "football" was originally ambiguous enough to also refer to rugby, which is why England coined the term "soccer" to distinguish the two sports. American and Canadian football are both descended from rugby football.
Because the audience of HN is not just Americans and the title of this submission gives no clue it's about the US.
