Ah, right, so you believe that the entities that Wiccans worship do in some way exist, but that they are actually demons, not benign gods.

I should probably point out at this point that Wiccans (well, at least those whom I'd met), consider this point of view utterly misguided and incredibly offensive. No one likes to be called a "demon-worshiper", especially when one is generally a nice person whose main tenet in life is a version of "do no harm". You probably meant no disrespect, but flat-out calling a whole group of people "demon-worshipers" tends to inflame passions rather quickly, and not in a good way.
