Mothers keeping silent, victims keeping silent, and abusers feeling that they've done nothing wrong are more the norm than the rest of the world would like to think. There is often an unspoken conspiracy of silence within the family that allows this type of abuse to go unchecked for years - even decades and amongst generations.
BizzyBee, you hit the nail on the head with that comment.
Incest is a despicable crime that does run rampant in some families for generation after generation, it's even more despicable that the JW's who claim to represent god on earth allows it to happen and looks the other way.
