You don't have to be called a witch, to perform witchcraft. The vast majority of people do it every day, without realising they're doing it. Including many so-called Christians, who claim to serve the one, true God of absolute love.
When I was a child, my parents always told me, "If you can't say something good about someone, don't say anything at all." But God has taught me, if you can't THINK something good about someone, then don't THINK anything at all.
By the way, this cartoon is based on an actual encounter I had with the head witch of a coven, the full testimony of which, can be found in my book.
