Again, which you are loathe to do in other contexts when, according to their words, the truth is clearly not with you.
Really? Come on, now...that's not true. I don't take you or any Mormon as any kind of source to preach on Christianity, because I don't believe you follow it, but your opinion about things that you actually do follow does matter. I would take into account your opinion on Mormonism as a religion, on the BOM, on the POGP, etc. as being that of someone who knows quite a lot about those things.
But then if a non-Mormon has things to say about Christianity vis-a-vis Mormonism, they are "muting God", "doing theology by vote", "listening to sinful men instead of God", etc.? (These are all things that Mormon posters have accused me of personally for quoting the fathers and sticking to the definition of the Christian faith held throughout the world prior to 451 AD, as would be expected of a Coptic Orthodox person.)
You don't see how this is incredibly hypocritical?
Well, you will notice that I am not commenting approvingly on the video, (a) because it is not something that I know anything about, and (b) because of it's inaccurate according to people who actually know Mormonism (Mormons, not the B'nai Brith!), then it shouldn't be approved of just because it was produced by Christians. I have noticed, however, that the response from other Mormons in this thread isn't that it contains no truth whatsoever, but that is exaggerated. So I would want to know what it got right and what it got wrong from a Mormon perspective before I could really evaluate it. (Which honestly I'm not even interested in doing; it's a random YouTube video that is apparently popular with Evangelical Protestants, but I'm also not one of those, so I don't want to spend my time watching videos that they produce about Mormonism when I can just ask a Mormon about what they believe.)
See above.
Their contradicting Joseph Smith is of no consequence, as Joseph Smith is a non-person in Christianity. You might as well say they contradict Muhammad or the Dalai Lama or whoever.
As far as their contradicting each other, I'd need to see some examples to know what it is you're even talking about. Please bring a few examples and we can discuss them, if you are interested.
