Pagan (living naturally)
i think you have the modern meaning of pagan, rather than the traditional meaning..
Most modern religions and their festivals are pagan in origin (original pagan meaning)
but how they are celebrated the original knowledge is lost..
Paganism, or living like pagans, is following nature..
Modern religions do not follow nature at all. (well they do, but they dont want to make it so obvious to the follower of teh religion)
