Christmas has lost the religion part a long time ago, its just a day to give back to people you love and enjoy a nice dinner with family, simple as that.
Christmas is what you make out of it.
Ifs up to you to participate in the version where you need to buy presents for people you dont like or even decacent presents noone needs for the people you like and have to have that monster christmas tree because your neighbour also has a big monster tree..
Or if you just have a good time with your family, without any stress and some holiday, where you sleep longer, eat much and celebrate your family instead of the unreal birthday of a fictious christian prophet..
And its up to you if you tie it to religion or if you dont..
This has gotten way out of control.
Closing.
