Yes, Happy Holidays - not because it's politically correct, read a few of my posts, I could give a shit about pc-ness - because we celebrate more than one holiday in our home, we have friends who celebrate different holidays and for YEARS, yes YEARS, I have chosen to wish people Happy Holidays, or actually to be more exact, I usually tell people to "Have a Great Holiday".
I am never offended by being wished Happy Hannukah or Merry Christmas, the person making the wish means to give me a word of cheer. Wouldn't it be wonderful if people meant to give words of cheer more often? No one wishes you a cheerful day and means to insult you, sure you may not celebrate that day, but actually, for those who don't celebrate anything, are we insulting them by wishing them a happy anything? You never hear them complaining (about that... yet).
The intention is to be cheerful and kind, and so, those people who are having a fit about people taking the Christ out of Christmas, they need to think again - that may not be anyone's intention at all. And if they are such devoted Christians, then kindness to others should be much higher on their list and prevent them from being so insulting and rude and judgmental. I'm sure a good many of them haven't even thought of it this way, they are concerned about the twice a year Christians, or those who don't even worship watering down what is to them a religious observance first and a gift giving egg nog drinking party second (or they want to pretend that it is), and they have a right within their own family and home to make sure that the religious observance comes first - they do not have a right to make others feel dirty for trying to be kind to all, including Christians and non Christians who are also celebrating a holiday, and in the case of Hannukah, a religious observance that is thousands of years old and is much more about the celebration of faith than gifts and food (although Latkes are probably as much looked forward to or more than many favorite Christmas treats in our home).
