James Gardner and Englishman in the early 20th century established what is today known as gardnerian witches. It was his idea (wrongfully) that the ancient religion of wicca had become extinct (not so, witches just went underground). Most Gardnerians witches are introduced into wicca with the assumption that what they practice is witchcraft. Most traditional witches remain secretive about their religion and don't go around advertising it.
I got curious about it when I saw one of my customers wearing a pentagram around his neck. That led to my curiosity about modern witchcraft and it was a nice distraction from my Marxist studies at the time. It seems that there is a world stranger than demented leftists out there.
Of course I suspect that Hillary is a Satanist rather than a witch.
Hmmmmm
