You can also say a lot about stuff like Wicca and its dogshit creator, but I've known a few witches to also get involved in stuff.

As a Wiccan, I can confirm, Gerald Gardner was a weirdo little freak who sucked major ass. He gets credited with codifying the thing we now call Wicca, but his contributions tend to get overblown, since tons of that stuff was done by other people, especially women, who were a part of that movement. Women who were, by and large, cooler than he was.

Also, one of the more important primary source texts that influenced Wicca's development was Aradia, The Gospel of the Witches, wherein the Goddess Diana gives birth to a messianic figure named Aradia, who teaches oppressed peasants how to do magicsl class Warfare, which basically boils down to sabotaging crop yeilds, and poisoning priests and lords. It's incredibly cool and based.
