The holidays are always a hectic time of year. You have to buy gifts (if you celebrate Xmas), see relatives you might not normally want to see, and gain a few pounds from all the eating and drinking you'll be doing. The main holidays going on are obviously Christmas and Chanukah. And of course like every year there is an argument over whether we should wish people "Merry Christmas" or "Happy Chanukah". The pc way to go about is to wish people a "Happy Holiday" or "Seasons Greetings."
As I've mentioned before, I'm not really religious. I grew up Catholic and I hold some of those values, but I don't go to church. Obviously, I celebrate Christmas. I don't celebrate the religious aspect of it, but the perfect timing to catch up with old friends and family. I don't really bother with the whole "People might be offended if the Christmas tree is actually called the Christmas tree" crap. Or for that matter if an atheist might get offended if I wish them a Merry Christmas or Happy Chanukah.
I use to worry about it a bit when I worked in the restaurant industry. People love letting the server know they are wrong on something. I guess it's the whole servant thing. Nowadays, I think it's rather frivolous. I also don't really get bothered if I see a Nativity scene in the middle of town.
Granted, there are other celebrations going on like Kwanza and the Soltice. But does this mean that Christians and Jewish people can't express what is a religious time for them in the public eye? Do you think I would be insulted if someone wished me a Happy Chanukah or Kwanza? I just feel it is a waste of energy. People get worked up over the weirdest things at times. Get aggravated with the war going on not over a holiday celebration.
Celebrations whether public or private should not be misconstrued as an insult or threat to the separation of church and state. Celebrating the birth of Christ (even if you don't believe it) is not a horrible aspect. Whether you like it or not, Christmas is a federal holiday. Which means that it's an in-your-face type of celebration. Don't be a scrooge. Christmas has become very commercialized, which you could even separate it from the religious aspect of it. I have friends who are just like me that aren't religious and we have the best time during Christmas. This is especially true of the little kids. They are only interested in Santa Claus and what he's leaving under that Christmas tree.
