Not sure how we "lowly" uncivilized American's can be considered both crude and prissy.
In the US, we use American English. In the UK, you use Queen's English. Two different countries and two different languages. Do you all make fun of all other countries that speak different languages?
I don't see anything making fun of Canadian English. How about Australian English? Those both came from Queen's English but have also been changed over time. Or do you not make fun of those countries because they are Commonwealth Countries? They must very well still be civilized since they are Commonwealth Countries. Us poor uncivilized American's don't know any better do we?
I am surprised you don't look down more on Australia. All those British criminals in their pedigree.
If you do not want to adopt language nuances from other countries, you need to look inside your own borders as to who is making those decisions and connect with them. Is it your media? School systems? It certainly is not any American who came to your country and forced it.
The majority of American's say Merry Christmas. We do also recognize that within our 300+ million person population, we have various religions who celebrate major religious holidays from the first part of November until January.
We wouldn't want to leave out all the people we have welcomed to our shore, like the Jewish refugees during World War 2, Buddhist refugees in the 70's and 80's, and the Muslim refugees in the last 20-30 years.
Here is what is funny, it has been my experience in the US that Christians will say Happy Hanukkah to our Jewish Friends and vice versa. That happens across all religions here.
That doesn't make us woke, it makes us respectful to our fellow humans.
