It's very likely that someone who can't see any values in women besides fuckable holes did not grow up with a loving motherly mother. (which isn't their fault). "what would your mother think" does not work on anyone who's mother was a neglient slut that brought in a violent stepfather. Or who was physically or even sexually abusive. There is reason why they can't think of "being motherly" or "caring for children" as possible values for a partner.
