Thank you so much for the clarification.
Setting aside the plural marriage thing (which wrecks it from the get go on it's own), even with the law being changed to 16, they can't give their daughters to be married if the marriage is not what the daughter wants.
My understanding, from reading the widely published experiences of women who have left, is that the leaders decide on the marriages, and they take place even if the child disagrees and has to be forced.
Forcing children into abuse at the hands of an outside party is never legal.
That’s why I keep saying these aren’t marriages. If one party is forced into it and does not wish to do it, all holy words muttered over it won’t make it any less rape.
