If you're a Christian or a Pagan, I'd say be happy that X-mas is being used instead of Christmas or Yule
It'd be offensive otherwise.
May it's because the holiday is less about religion now that it ever was, is this because our society is more secular or because most 'Christmas contributions' are actually from other religions and retail giants like Wal-Mart?
Then again, maybe the reason why X-mas is because used is that even so called 'Christians' have forgotten or missed the point of this holiday.
It's not about 'I hope my gift wrap is big and shinny', it's allegedly about giving goodwill to others and other 'hippy stuff'.
Then again, maybe I'm nuts.
