Well, in that sense, I see how you feel. I am torn by the fact that authorities will act on a tip and in turn destroy the secure home life of a child to put them in much greater lasting harm than anything they may have experienced in the so called abusive situation. I once worked as a counselor in a youth home that accepted wards of the state. Nothing could alleviate the anguish those boys experienced in that hostile situation. I will never forget Tommy and Jimmy, brothers that were place there by a judge because of their parent's custody battle. Catch the pervert and put him in prison! Don't incarcerate the child or mother.
Many of those children in the compound don't know who their parents are, or where their parents live. In this cult the humans are components and can be reassigned to different units, even the children can be reassigned as some were to this compound. The female children are being bred and raised to be used in marriages, the males are sometimes kept to serve as husbands and leaders but are also thinned out mercilessly when they come of age to compete with the older men for the carefully cultivated girls. There is no security, these people are not a family unit. The cult is evil, not different, this is a rescue.
I agree: ripping these children from their parents is about as traumatizing an event as could ever happen to them, perhaps equal to whatever sexual abuse some have experienced. And what of the children to whom no sexual abuse was perpetrated? They are now scarred for life just as deeply. I am speaking from first-hand experience, here, not just spouting an opinion.
