"What strikes me is the vehemence of the letters I receive, the hate mail, regarding having a witch on our faculty. I thought that the burning of witches was settled several centuries ago. But people write me and sign it "a good Christian", "an ecumenical Christian". They say "you and your witch friend can burn in Hell forever". It's just amazing what this brings up — that there's a lot of buried material in a lot of Christians' lives."
