I think why they added it was because comics were very popular in the 80's. They would sometimes use the symbol in their comics, and make it into something else. Take Manga and Anime for example. They used the Star of David as a symbol of magic, which idk why. As in matter of fact, I'm actually open to all beliefs. I have to agree that they should of never made it look like that the Wiccan's are the bad ones! Who ever it was must of been a pure Christian, and must of really hated Wicca. For that matter, they should of never painted it, cause think about the children!
