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...
Oh good God! This is not rocket science! If the "FOUNDER" of the religion has been shown to have lied as to the basis of their "denominationation", then the whole foundation is ROT! We are not talking about some petty doctrinal issue hundreds of years later by some "adherent".
Oh, don't leave the atheists out of this. Atheists may have gotten a late start, but they have done their best in modern times to run up the body count. Lenin, Stalin, Mao, Pol Pot, et al., were self-proclaimed atheists and mass murders all.
So do I blame all atheists for the crimes of a few? Of course not. Some of my closest and dearest friends are atheists who are good people by any standards.
I do not believe in collective guilt. Any large group of people is likely to contain its share of scoundrels.
