It's all the rage in backward African countries where American evangelists have plied their magic - homicidal homophobia.
It begins by a couple of cracker shamans (like Scott Lively, author of "The Pink Swastika") staging rallies at which they convince the locals that the homosexuals in their midst pose a dire threat to their children and their society. Once the idea sets in, the rest pretty much takes care of itself.
Their biggest success so far has been in Uganda. But this weekend in Ghana five attackers, one of whom was an evangelist pastor, seized 72-year old Ama Hemmah, tortured her into confessing she was a witch, and then doused her in kerosene and set her alight.
