As an atheist, I celebrate Christmas. To me, it is a holiday that allows us to get together with our friends and families and bond with them. Regardless of if you are an Atheist, Agnostic, Protestant, Catholic, Jewish, or any other religious stripe, we should all endeavor to get along for one day a year.
Edited to add: Thank you to all who commented on this blog, wishing me a Merry Christmas. I was unable to respond, as I was working, and we do not have internet access at work. Again, thank you. I hope the coming year brings all of you happiness and prosperity.
