I am a Brit, but I live abroad.
I think your line “people who are advising you to be more politically correct in your complaints are probably the same people who think the French and New Yorkers are rude” sums up the position quite nicely. I might substitute ‘more politically correct’ with ‘ less direct’, but your meaning is spot on.
The best complainers are the Dutch, the further north, the better 😉
Have you read the ‘BA withdraws….’ thread? Thanks BA, for pulling a useful offer and we better all get used to this change.
