“An aunt of mine came visiting two weeks and got upset with me for hiring a house-help from a region known for witches. Is witchcraft real or some sort of psychological craze?”
I am not sure which region is known for witches, and therefore not sure how your aunt came to such an amazing conclusion. Lay people are in some ways privileged because in exercise of their responsibility as lay people, no effort is required to show any evidence for the “lay” position they hold. When one says that a certain part of the country is full of witches, while the other is full of highly educated people, no evidence is required to prove the point. It is enough to state that opinion.
