How do you leave the Catholic church and the Orthodox church out of your attack, both have the same position on Mormonism as all Christian denominations do. Pope John II personally ruled on Mormonism, do you share his views, or the Catholic teachings on Mormonism?
I'll renounce Mormonism as a false religion but I don't see what that has to do with Mitt's ability to execute the office. I reject Mormon baptism as an entrance into the family of Christ. I don't know specifically what JP II said but I'd imagine it was along those lines.
What difference does it make to me if Mitt is motivated by a desire to become a god? I haven't seen him motivated to do anything outrageous - he's a flip flopper but I figure that's because he's a politician, not because he's a Mormon. Mitt's not my first choice, but right now he's all we've got - what is it specifically about Mitt's Mormonism that prevents him from being a good president?
So far, I've just seen a bunch of folks pointing to all the wacky stuff Mormons believe, not specific details, e.g. a desire to impose Sharia.
