Perhaps hundreds of millions of people live in freedom because of him. Having the luxury or knowing all that Reagan had done, had he been a Mormon, you would not have voted for him, would you? If not, that is a pretty sad commentary on you and bigotry. As a Catholic, I am not threatened by Romney's religion. I am, however, threatened by his policies with which I greatly disagree. That should be the argument. Mormons whom I have known in my life have been pretty much decent people who raise good, respectful kids. Are Jews acceptable to you? Buddhists? Hindus?
NONE of these groups claim to be 'christian'; and the only "TRUE" christians at that.
MORMONism is a heresy; no matter HOW fine someone's neighbors are that are deceived by it's seductions.
