My favourite argument I have heard a few times over the years on this site is: 'I was researching my family history and I'm related to one of the witches from Salem! She was a Wiccan who was burned for her faith.' I love when people say that, I just chuckle and think 'go on.' Because a quick Google search can prove that statement wrong. It's still fun to see how many people were Wiccan. I suppose Gardner was a time traveler who felt like messing with people.
It's been a while since I brushed up on my Salem trials, but the only 'witch' was a Caribbean slave. In all witch trials [in Europe and Salem] it was based on hearsay and hysterics, not facts and evidence. Got to hand it to the medieval justice system though, they always got their man! [With a little 'persuasion' of course.]
