Do you have any proof whatsoever that they were excommunicated by the LDS (not Mormon) Church? Especially the children? If so, I would like a link.
Besides they came from the Arizona Strip not Utah, where they have also been in a sort of prison. Jeffs was in the process of taking the younger ones to Texas for a new crop of sex brides. Problem with Arizona and Utah for that matter is they have been looking the other way for much too long regarding these sad and strange folks. My belief is that because the COJCLDS still believes that the practice will be theirs in the afterlife, they are sympathetic. Good luck having it both ways you bright apologists.
The church excommunicated the perps, not the children. Of course the children were never introduced to the modern Mormon church, so they are not regarded as LDS either.
If you really want substantive answers to your questions, I suggest you contact the Mormon church yourself. If you are simply making implied statements camouflaged as questions, I'm not interested.
