Hi Qcmbr.
I think the point that was coming across in the doco was that she told her mother and HER MOTHER claimed that. She just didn't want to believe that it could have happened. And she ended up shunning her daughter in the long term.
I think the similarity here between dubs and mormons is that they just don't want to believe that anything like that could possibly happen within their own church. I am not familiar with child abuse scandals in the mormon church either. I guess my point is what I stated above.
By the way I am sorry about your uncles neice.
