It's a little like that in the UK as well but not as bad as it seems to be getting in some US States, California in particular I hear.
Let me state that I'm totally non-religious but Christmas is part of my culture, I grew up in a society that is/was mostly Christian, the crusading days and Spanish Inquisition are history, nowadays them Christians seem mostly peacable to me so, yes, Christmas is cool, something to do in mid-winter innit?
All the muslims/hindus/buddhists/jews/wikkans/whatever I've spoken to don't find me wishing them a Happy Christmas offensive, it's just these loony (mostly local) politicians who think they're doing them a favour by trying to outlaw a festive greeting. Crazy.
For myself whenever I wish somebody a Merry Christmas I'm thinking inwardly 'happy midwinter' or Happy Solstice time'.
And cirianz, I did read somewhere that using Xmas is actually Ok, apparently it may have been the original greeting for celebrating Christ's birthday. Wish I still had the link to that, but I haven't.
I could go on, say most scholars reckon JC was born in August, say that I think he did live as a prophet/hippy/all round good geezer, say the Christians hijacked a Pagan ceremony, but I won't.
Suffice to say it's a horrible bleak time of year and Christmas is a damn good way of brightening it up
