So by her own admission she ‘wasn’t forced into a marriage with an older man against her will’.
Legally, her consent is irrelevant. It's called statutory rape. And if it is a polygamous "marriage", it's not a legal marriage, therefore there is no consent to be given by the parents of the minor. String the perp up with Warren, maybe they will get married to each other. Who knows?
If such an event happened.
However, by her admission, in her case, for some reason it did not.
So in this specific instance, there is no 'perp' to get yourself all lathered up about.
