I think that part of it is due to the patriarchal nature of these religious organizations. If you look at these occurrences there is one constant regardless of the religion - you see the same things whether you are looking at Waco, Strong City, FLDS, the Jehovah’s witness cases, or the cases within the Catholic church.

The difference between the cases in the Catholic church vs the fundy cults is that at least the Catholic church recognizes that child abuse is a sin and wrong in principle if not in practice.
