Hmmm.... "Pagan" is based on the Latin "paganus", which basically means "country dweller". With man's ability to mutate word meaning over time, I find it strangely humerus to think that a couple hundred years from now the word "redneck" could have a similar religious connotation!
Anyway, back to the question... I sometimes refer to myself as Pagan because I find my beliefs are outside the established norms of the recognized mainstream religions (Judeo/Christian/Islamic). And since thats is the current meaning of the word, then surely that must be what I am.
What I would find interesting is the reason for the question. Have you foudn a new internet self measured study that indicates "Pagans" more likely to have large penises?
