Heh...my first girlfriend was a Wiccan and even she (who was an educated and intelligent woman) believed the whole burning times thing; it was part and parcel of her religion's history, she said, that they had "always" been a "persecuted minority." That was the first stumbling block in our relationship (long before we considered dating), when she found out I was Catholic, because to her the Catholic Church was the All-Powerful Woman-Hating Witch-Burning Monolith of Evil. She also hated anything to do with the (pre-Christian!) Roman Empire because, as she said, they stamped out Celtic paganism in favor of their own pantheon.

And as much as we learned about each other's respective faiths, which I would say is quite a lot, as far as I know to this day she believes that stuff.
