Quote - It's all about good will towards your fellow man, and enjoying that feeling with others

I agree.  While I may attach certain personal, religious connotations to "Christmas" I would always say that the spirit is one of good will towards all and sharing a common experience of that together regardless of any other significance, or lack of it, someone may personally attach to it.

We can all celebrate it together no matter what our religious beliefs or lack of same.  Everyone knows what "Good Will Towards Their Fellow Human Beings" means, I hope.
