Well, there's Vivi, who has already explained enough regarding her lifestyle and the tedious stereotypes that comes with it, and there was HG, a former member, who was apparently practicing witchcraft while it coincides with her Hindu faith -- it's an open-minded religion, after all.
I'm not really into the idea of witchcraft, but I'm hardly bothered by it. Then again, I'm not really concerned with other people's way of life, except for when they belittle mine.
