I believe incestuous rape is also quite common in Western societies, maybe not as common but still a big problem.
I know of three families that lived close to my parents that fell victim to incestuous rape, all within a two mile radius.
The usual lynch mob appeared outside the houses and the whole family, victim and all, had to be removed for their own safety.
I never did find out what the end results were because of the laws regarding disclosure of information in reference to minors.
It's quite scary that we live amongst such people without ever realising what monsters really they are.
