Why do we, as Mormons, have to play this game of "I don't know why the doctrine was given to bar blacks from having the priesthood"? It is a silly game to play.
Because anti Mormonism, by definition, has to be very nuanced in order to maintain the deception. Such nuances include much that isn't doctrine.
IF we believe that the Mormon church has the truth, the whole truth, and nothing but the truth (I feel like I'm giving testimony in court), then shouldn't we also acknowledge the truth about when we get it wrong?
Sure. Feel free to point out where I am wrong.
I think there is this misconception in the Church that possessing the truth (or I'd like to more clearly state that the Church should be about "seeking the truth") makes the Church and its mortal leaders infallible.
I think we ought to treat them like we treat the ancient prophets; fallible men who nevertheless made it work or got the job done.
That belief just sets one up for failure and ridicule. Human beings and as a result the organizations that they are a part of are highly fallible. With that proper understanding, I don't see why we, as in Mormons and the Church, just don't come clean - state it was a man-made doctrine introduced by racists (of which I absolutely believe BY was one) - and apologize and move on. Being dedicated to discovering the truth is about being able to recognize one's mistakes, acknowledge it, learn from it, and move on from there.
The nice thing about all this is that the LDS Church has a Systematic Theology with a clear and absolute identifier for doctrine. Because of it, we can easily separate out the fallible man from the prophetic statements. Notice that I did not have to deny the Newsroom article (beyond me why anyone would think I'd have to), I simply relied on the doctrine. I take the Church at it's word and apply all of them. I believe it (my testimony).
