It also isn't what you or bullies like butchersapron choose it to be - at best this is a discussion in which finding out what it might mean is arrived at. If you're talking about particular festivals with Christian elements, if you reject those Christian elements of them, I am here saying that you're not in any meaningful way culturally Christian. To insist that you are is very dodgy, and exactly the line that the likes of phildwyer take in insisting that people are Muslim, babies can be Muslim etc.
