I don't think that 77% attend church once a week
Maybe no - but I can't get over the fact that 86% reject gospel doctrine (D&C 132? - polygamy) and call polygamy morally wrong! Is this hypocrisy or something else?
It's not a contradiction, Jacob 2:27-28 clearly says that a man will only have one wife and that polygamy is an abomination, There's not hypocrisy there. But polygamy being immoral certainly would have been news for the first seven presidents of the church.
