Depends on why you are celebrating Christmas
If you're celebrating Mr. Jesus' birthday, then it's down to you and what you feel is appropriate.
To me, an extravagant Christmas is not something that I would ever consider necessary. If Jesus really is still alive somehow, then I really doubt he would be more impressed by a bigger Christmas budget. I would like to think that he is happier when we actually remember that it is his birthday we're supposed to be celebrating.
But if you're just celebrating Christmas because of it's traditions, well then I really don't give a fuck what you do....
