That's not the point. IT IS if someone is willing to buy "whole hog" into a religion that is based on on foundation of lies and deceit, you have to question their capacity to think clearly. I have known many Mormons who are the greatest people... but what I just said stands by itself.
So, basically. what you are saying is that anyone who is a Mormon has diminished capacity for logical thought = because the Mormon Church (The Church of Jesus Christ of Latter Day Saints") is "based on a foundation of lies and deceit".
I take it you are an atheist? Or have you found a church with nothing in their history to question. If so, enlighten us.
If not, then my first assessment of your remarks still stands - you are judging a person on the 'sins' of their church....which would leave the majority of the worlds population with questionable 'capacity" including you - unless you an atheist...
