I definitely can appreciate the meaning Christmas has to Christians, As I was raised in a church till I was 11 and have read the Bible a few times. But, It is commercialized completely now, I think some non-Christians look at Christmas as a time to spend with their families and be thankful and giving.

I mean to Christians, wouldn't the Christmas tree, Santa clause and flying Reindeer be false magic and in some ways demonic. Santa if anything, is there to take away the "true" meaning of Christmas.

Also, It was originally a Pagan holiday that the Catholic church combined the two together.

So, I don't think it's wrong for non-Christians to celebrate the holiday in their own way.
Also, I'm not an Atheist, I do believe in a Creator, Just not the same way as religious people do.

The hero and the coward both feel the same thing, but the hero uses his fear, projects it onto his opponent, while the coward runs. It's the same thing, fear, but it's what you do with it that matters. Cus D'Amato
