Xmas is suppose to be a Christmas holiday for Christians, but over the years due to commercialism everybody becomes a part of it and it is no longer Christian.
I'm sure there are accomadations for people who want to celebrate it in an orthodox way. But you can't expect everyone to become "Christian" for a few days every year.
You can either spread Xmas cheer with everyone by being accomadating or stake sole ownership of it and exclude everyone other than the believing Christians. Can't have it both ways I guess.
Personaly I do find it wrong about simple things like people wanting to change it to happy holidays from Merry Xmas or like stated here winter festival. I wish many of my Christian friends Merry Xmas every year. If that makes them happy why not just as many of my Hindu, buddishts friends wish me Eid Mubarak ( Which none of you buggers did here

). Another thing atheists getting all up tight about in a useless battle to one up the theists.
But in mixed community events Chirtstian specfic stuff should be minimised I feel. Like nothing wrong with frosty the snowman. I'm sure children arn't learning anything religious from these thing anyways. Plus you can teach them at home, sunday school, mass etc etc.
Trust me I know how it feels. Although its a Muslim country but Xmas is celeberated with more fervor here than any of the Muslim holidays. Although officialy its not even a Holiday. But most staff are given days off or half days etc etc.
Just my 2cents.
