I read a book once about how to practice Wicca that included a lot of nude ceremonies. However, the impression I got wasn’t that they were preserving an ancient way of life, but rather that this old bearded dude was taking advantage of the young impressionable women and boning them “ceremonially”. There were many parts where the ceremony is temporarily suspended while the grand master and his chosen retire to a separate room before returning and having him choose a different girl. It was very cultish. I thought the prominence of the guy was kind of weird for a religion that’s supposed to be so maternal.
One bad book doesn’t condemn a whole class of people, but I was surprised that it was published at all given how it made the author look. I’ll have to look up the name of the book when I get home and see if it has been disowned by the majority of Wiccans or something.
