Mormons were founded by child rapists (Islam too). Don't really see how one can respect that religion.

Joseph Smith and Mohammad took child brides. Mohammad had some as young as 9 years old. Smith had 4 that he married at the age of 16 or younger.
I believe it. Very grizzley and manipulative, indeed. Having said that, I'd like to pick your brain for a moment, if you wouldn't mind.
I can only assume (in the name of consistency, of course) that you don't see how anyone can respect Christianity. After all, surely you do not deny that some of Christianity's forerunners engaged in some sexually peculiar practices in the Bible as well. Please correct me if there is something incorrect or inconsistent with your reasoning, otherwise, I'll take it as given.
I'd also be interested in hearing your thoughts on Felix Rex's point concerning the founding fathers' affinity for the practice of slavery, particularly Thomas Jefferson's? Is this scenario at all analogous to the brutal origins of Islam and Mormonism? If not, why? If so, how has that impacted your view on the contemporary US?
