The basis of Mormonism is no more illegitimate than the basis of any relgion

[Starbucks Union Thug HokeyPuck]

Yes, the BS spewed by Joseph Smith in his disciples is no more ridiculous than the story of Genesis.. except when taken into context. 

Mormonism was created a couple centuries ago by an ego-maniac with a ridiculous story.  We had made quite a but of progress as a species. 

Judaism and its offspring were created in the uneducated villages of the desert thousands of years ago... before even a semblance of reason and science had been introduced. 

Not only that, but I have no way to unequivocally prove to you that Jesus did not exist and was not the son of God.  I can prove to you that the Native Americans are not a lost tribe of Israel.  The only word to describe the tenants of Mormonism is "silly".  I give mainstream Christianity a little bit more credit.  Not much... but some.
