What a disjointed article.  The headline is "How an atheist celebrates Christmas", and the first paragraph and a half talks about atheism, then the author goes on to espouse he is a "secular Christian" and the remainder and majority of the article is about his respect for Jesus and Christianity as a faith, along with some debatable bafflegab about the history of Christianity.

I am an atheist, that's why this article interested me.  I have respect for Christianity and Christians, and how many Christians have done good for their fellow people regardless of faith in the name of God.  I may not believe almost any of the Bible, and loathe people of any faith who try to impose their religion on others, prefer a secular state, and loathe organized religion but one's faith or spirituality is a personal choice and I respect that choice.

I personally do not celebrate Christmas as a day when the saint Jesus was born.  I look at as a time to enjoy one's loved ones and a consumerist holiday.
