In short then, there is not now, nor has there ever has been a war on Christmas. In most countries of the world (yes there are some exceptions) you can celebrate Christmas as you wish, and sing the songs you want, and make greetings as you want. The fact that some say Happy Holidays in no way diminishes my belief that December 25th is a special holy day for me. Saying happy holidays however recognises that mine is not the only game in town. Some people are atheist and agnostic, or are Hindu, Jewish, Muslim, Buddhist, Sikh etc. The store clerk who says Happy Holidays is not saying that Christianity is worthless, but rather is saying, "I am not sure what if any religion you practise, so let's just play it safe and wish you a happy holiday." I, for one, am not too proud to take any good wishes for granted. Blessings.
