It's not as big a deal there because the legacy of the Puritans (who banned Christmas, and almost everything else worth enjoying) is much stronger in the US than the UK. While the UK (England as it was) declared the draconian Puritan laws null and void in 1660 (ending the ban on Christmas (see the BBC link below), football on Sundays, holding hands while dancing, theatre, drinking/toasting etc. etc.), Puritans across the Atlantic had a much greater grip on power. Christmas didn't become a federal holiday in the US until the 1870s.
In 1917 the US writer H. L. Mencken wrote that the US had not cast aside the pernicious Puritans influence: "The Puritan's utter lack of aesthetic sense, his distrust of all romantic emotion, his unmatchable intolerance of opposition, his unbreakable belief in his own bleak and narrow views, his savage cruelty of attack, his lust for relentless and barbarous persecution – these things have put an almost unbearable burden up on the exchange of ideas in the United States."
Three years later the US had prohibition (no alcohol). Even today you have to be over 21 to drink there. Having extreme religious views also transfers into other aspects of society, such as attitude to race. The Ku Klux Klan (white, Christian nationalists) an example. The emergence of the second era Klan was triggered by a film (that's all it took)...Birth of a Nation (1915)...the black character (white actor in blackface) in the film was the villain of course (portrayed as a rapist)...with an audience member firing shots at the sceen to "save the white woman" running away from him. After the film four million people became Klan members, partaking in religious symbolism (cross burnings) as well as lynchings etc.
The Virginia trial court Judge Leon Bazile, who in 1958 charged Richard and Mildred Loving (interracial couple) with a felony (interracial marraige was illegal there until 1967) he defended his decision by invoking God: "When Almighty God created the races white, black, yellow, Malay, and red, and placed them on separate continents, and but for the interference with his arrangement there would be no cause for such marriages. The fact that he separated the races shows that he did not intend the races to mix."
The Puritan legacy of guilt associated with sexual relations outside marriage...a teary Tiger Woods being wheeled out to do a press conference in 2009 because he had cheated on his wife (utterly surreal, wtf has his private life got to do with the golf or the public?).
Puritans were an extremist, persecuting cult, and that cult-like influence has been a major part of the 13 colonies/US landscape for centuries, as opposed to England where their reign of terror only lasted a few decades and ended in 1660. Christian fundamentalism, the bible belt, the megachurchs, the televangelists, the reciting a pledge every morning at school, the politicians having to publicly declare their faith (its everyone's business there, and you must have a faith otherwise they have no chance of being elected), nutters like Marjorie Taylor Green and Lauren Boebert getting elected, Alex Jones, the latest school massacre followed by that very effective response of "thoughts and prayers" ...the legacy of an extremist sect, from the 1600s, goes on and on there.
