Right side up pentagram= Wiccan
Upside down pentagram= Satanism
Wiccan is not necessarily Satanic. It's a new religion founded by Gardner, somewhere back in the 50-60's.
I have and have read Gerald Gardner's book on Wicca. I didn't get the impression he was pushing a Satanic message throughout his book. It was more about the relationship with the God and Goddess and the relationship of Nature.
Whatever, at this point, it's your/mine opinions. And how you contextualize it.
