Who got yelled at for saying Merry Christmas? I disagree that there's a war on Christmas, it's absurd. You can say whatever you want, and it's not going to offend anyone. Stores try to cater to the diverse crowd that shops there because we live in a diverse country. They have a right to use whatever slogan they want in their advertising. But if you go into those stores, how many menorahs do you see? Any Kwanzaa decorations or cards? How about any Islamic holiday items? I see Santa Claus, Christmas trees, Christmas cards, Christmas wrapping paper, candy canes, lights, etc. So what holidays are being censored?
They can say anything they want in stores, and you can say anything you want when you go home. It's called freedom. Isn't that what we celebrate in this country? I think there's more important issues to worry about.
P.S. I think stores have done more to ruin Christmas with their over-commercialization of it than anything else. I'm sick of seeing Christmas decorations at Halloween. The holiday is all about buying stuff, and that's it. How can Christians be so concerned about semantics, but not want to fight a "war" against stores that are trivializing this most holy of holidays??
EDIT: I want to thank you for your comments, you seem intelligent and like you've thought this out, and I respect that. But if we don't censor Hannukah or Kwanzaa or Eid-al-Adha, we definitely don't censor Christmas! When was the last time someone wished you a happy Eid-al-Adha or a kwazy Kwanzaa? :-)
We don't have a state religion and we never have. That's a very dangerous thing - ask Iran and their morality police.
