I'll give you an easier target, if you're into the Bible: Halloween.
I love celebrating Halloween. Guess what? I don't believe in demons or ghosts or Satan, either.
Wrap your head around that one, will ya?
PS: I celebrated holidays BEFORE becoming a JW at age 10. So, I'm just returning to the traditions of my forefathers. I think you're reading too much into the whole thing. Perhaps getting a little too much exercise by jumping to conclusions. Certainly, you're not persuading anyone here, that the celebration of traditional holidays by non-believers is somehow 'wrong' or 'delusional' or 'hypocritical'. Free your mind. Think for yourself. It's difficult, but enjoyable.
