Child molestation is not "aside". Child-rape (it is not "molestation" it is rape) and enforced sexual slavery are the central point of this action.
The FLDS would have been tolerated ad-infinitum if all they did was practice polygamy AMONG CONSENTING ADULTS and keep it to themselves.
Bullseye! I could care less about the polygamy angle as long as it's between consenting adults and they are raising and educating their children in a reasonably healthy environment. Girls under the age of seventeen having children with men more than three years their senior is the threshold of statutory rape in Texas. A reasonable compromise in my opinion. Find the men who broke this law and prosecute them. Return the children to their mothers and make it clear that we are watching. At this point, I think that this would be the best way to go.
