Days went by and I had a couple ideas. I could try it in form. Form seems to be good for humor. Since the generalizations about a group bug me I could recast it as musing on a specific (hypothetical?) witch. I may have had another idea but I'm not remembering it now.
The approach in version 2 below is a moving away from the Halloween witch, the Halloween cliches, toward the real fates of people accused of being witches. I'll have to brood on this some more.
