There is actually something in the Old Testament about not doing exactly that!
“When men fight with one another, and the wife of the one draws near to rescue her husband from the hand of him who is beating him, and puts out her hand and seizes him by the private parts, then you shall cut off her hand.” — Deuteronomy 25:11-12
Hah. Good old Deuteronomy...:)
So, this was rather common in OT times.
That one I’d still be in favor of.
