Wesley,

If you accept a Christmas present, this doesn't mean that you think that the holiday of Christmas has anything to do with a higher power. I treat Christmas like any other day pretty much. If someone says to me, "god bless you" I don't respond with anger but recognize where they are at in their belief system without condemning them for it.
But I don't believe in being discourteous to those that like the Christmas holiday.
Again, I recognize Christmas as more of a cultural event then having any religious significance. I see that the idea of giving at Christmas has become so commercialized as to negate it's intent by those that celebrate it.

I celebrate Halloween but I am not a devil-worshipper.

To recognize a cultural event such as a holiday is not to give to it any religious meaning whatever.
