Certainly she has a right to say anything she wants to ... but if the people that employ her husband don't like it, they can fire him.
If a wife wrote a column in which she described the management structure and owners of the Madisonville, KY hardware store where her husband works as "a bunch of nazis and perverts", he might find himself unemployed the next day .. how is this different than that?
No kidding! Especially if her husband says he agrees, as this pastor’s done. Yup, going to be some employment issues there.
