what's happened to Christmas

What has happened to Christmas, it is as if we are afraid to celebrate something that was once held dear to us.....in this day of political correctness we are scared of offending other peoples faiths and beliefs....but do we feel offended by there beliefs and faiths!!!!! I do not want to cause offence to anyone, but if we want to celebrate Christmas and we want to put up decorations and a tree, then why shouldn't we......surely being politically correct must involve all our communities.
we would be seen as racist if we started to complain about other cultures and religious beliefs, So give us a break, and let us celebrate Christmas properly
