I've not experienced this.
They'll IGNORE and SPIN; but the stuff is STILL in their 'scriptures' and in their History; where they CANNOT repudiate or renounce it due to being threatened with a Spirit of APOSTACY because of going AGAINST what one of the MORMON high muckety muck has said and taught.
Look at THIS and tell me what kind of feeling would race through YOUR heart, if you were a 'modern' MORMON...
"Now if any of you will deny the plurality of wives, and continue to do so, I promise that you will be damned;
and I will go still further and say, take this revelation, or any other revelation that the Lord has given,
and deny it in your feelings, and I promise that you will be damned.
Brigham Young - JoD 3:266 (July 14, 1855)
Well, I guess that covers everything ~ (laughing heartily).
