I see YA is telling me via a wiggly red line that I have made a spelling error.?

Not everyone on this planet is USA oriented. English was written and spoken long before the USA was envisioned. While I'm not begrudging the US spelling and grammar differences, why has YA inflicted this annoying indicator upon us. Surely they have the resources to be able to check multiple dictionaries, thesauruses, etc and be able to allow for differences in spelling between countries. If a word has different US and English spelling, give the questioner and/or answerer the benefit of the doubt and allow the spelling to go as entered. By all means use a spell-checker to bring attention to incorrect spelling but let differences between countries go.

Any comments welcome, for or against.
