KTO,
I have to agree with you, I can't remember ever being "offended". Must be their problem.
As for the "X" in X-Mas, I'd always heard that it was Greek for Chi. I can see Christians not wanting to use it. As for the Pagans who got the holiday hijacked from them in the first place, them, I can see using it.
Anyway, Happy Christma-hanna-kwanza-ramadon,
P.G.
