Because decking a smart-mouthed woman really shows manliness, right? Better to walk out and seek a divorce than to ‘give her one in the pie hole’. Also, islam is the religion that supports a man’s right to beat his wife (or kill her, for his honor), not Christianity.
No ‘’decikng’’ a smart mouthed woman shuts her up. You hit the nail on the head, ‘’smart-mouthed’’.
