Why is it wrong for ridiculous statements like these to be reported? If Romney got up and declared Mormonism the dominant religion of Christianity, there'd be hell to pay for it.
And yet one of the central tenets of Mormonism is that the established churches had become errant and corrupt, hence why the prophet Joseph Smith was chosen to be the translator of the golden plates. So either Romney does not believe in the tenets of his church, or he believes that all non-Mormons are also imperfect Christians at best.
I mean folks, if someone doesn't believe his religion is the best and all others come up short, why do they follow it?
