Being brought up as an atheist I still have warm fuzzy feelings about xmas and as I get older the one enduring thing I really like about it is the fact that most people really do get nicer, slow down for a bit and start thinking about other people. As my father in law was a vicar (minister in actual fact) until he recently retired my experience all round is that most of the traditional aspects of xmas do not really have anything to do with the religious aspects of it. It's a family time of year, a time to take stock and enjoy yourself and a great break in the middle of winter.
The one good thing that could come out of the severe political correctness this country suffers from
