One of the fundamental principles of Judaism is that G-d does not have a body.
I fail to understand, why the Mormons are being singled out over other Christian sects. Both violate this fundamental principle.
If you are trying to tell me that Mormonism is another Reason Not to Vote for Romney instead of a normal Christian candidate I disagree. If we don't have the option of someone who believes in the 7 laws of Noah, it makes no difference to us, if the candidate is a Baptist, Mormon or Catholic. What matters is his stand on the issues that are vital to us and to what extent we believe the candidate can be trusted.
And on the issue of Anne Frank, their Mumbo Jumbo words, have no halachic impact on her status and do not affect her relationship with G-d at all. Of course, if the Mormons ask me, if I approve of what they are doing, I will obviously tell them I do not.
In any case, I am more upset with the fundamentalists, who are saying Anne Frank is burning in Hell for not believing in Jeersus, than I am with fools that think she is in Heaven, because they said their Mumbo Jumbo.
