I'd call them dangerously loopy heretics who are well down the slippery slope to hell, Bob. A hell of their own creation, even if you don't believe in the literal sulfur-and-brimstone variety presided over by a big red guy with horns and cloven hooves. Which these people very likely do, but they think they're on the side of the angels, which makes them doubly bad.
