Fallguy, you make some good points. The difference, as I see it, in your case is you were both consenting parties. That was not the case in the compound.
Since when does pregnancy and marriage equal sexual abuse? When it involves 40 year old men with girls who are 13, 14 and 15, especially since the girls had no say in what was happening to them.
Why was it necessary to take the kids from their mother's? They allowed it to happen. I am not saying the women were not victims in this but that is not an excuse. For example.. I am not divorced but for the sake of argument lets say I am. My wifes new boyfriend or husband starts abusing my daughter and she allows it to happen. I would want her to spend as much time in jail as the guy who did the abusing.
I understand what you are saying in your last paragraph. Inner city teen pregnacy and marriage is a serious problem facing our society today. But you are still talking about willing participants. The girls in the compound didn't have a choice.
This is a very emotional issue. In a different situation I might argue differently. But in this situation, I think the right decisions were made.
