In Ghana, one form of violence against women that patriarchy has perfected is to accuse old women of being witches. A suspected witch is then sent into exile.
This article obsessively uses the word "superstition" in Africa to frame the problem. This cultural framing is not helpful. My immediate reaction is to talk about the 67% of Americans who believe in the devil. Not to forget those poor Salem witches that were barbecued in the New World.
A more helpful frame for understanding such an unjust practice is a feminist one, with the focus being patriarchy and violence against women.
