When it comes to issues of theology, there is an issue with critics of the church deliberately quoting unofficial sources, often sources that present fringe or heterodox theology (at best) as if it was official. This is why we make it a point to note whenever this happens so that we can try to point people towards what is official.
However, we're now talking about a matter of history, not theology. You yourself cited Fawn Brodie, which is about as far from "accepted" as one can get. It should be no surprise, then, that we use non-official sources to discuss history as well.
you are using an argument from assertion here. You assert yourself as official, while condemning all other sources that you don't like. Sorry, but you must apply the same arguments for both sides, you either are, or are not an official mormon source. If you are not, then your posts are 100% arbitrary, and hearsay, and not to even be replied to.
secondly, besides asserting your own posts as authoritative while dismission well known mormon historians and theologians like bringham young himself as not authoritative, you should really think about your position. What I do is examine every piece of argument for truth value. Not reject it because it is not official. You are guilty of labelling at this point, and this is why you will never win this argument. you are cutting off your nose to spite the face. ad hominem, fallacy. You attack my sources without actually discussing what was wrong. Again this is assertion as well, a fallacy.
some other fallacies, that I would verse myself with if I was you, which may help in the future....
Self-Defeating Argumentation:
A mechanics trainee (possibly dyslexic) was unbolting a piece of equipment at a manufacturing plant in western US.
This guy would loosen the bolt with his right hand. His arm would get tired so He’d switch arms. But Instead of loosening it he would tighten it. His arm would get tired so He’d switch arms again. He would start loosening again. And He did this several times, before the Mechanic lead pointed it out. A personal friend worked their and told me about that story, still laughs about it. But it’s a perfect example of circular reasoning and a decent example self-defeating actions:
The faster he worked the faster he undid what he had done already. The harder he worked, the harder he undid his work. Because in essence, he was fighting himself.
Self-Defeating arguments at their clearest. (spotting logic that simply self-destructs on its own without any refutation on your part).
(for example picking oneself up by their own bootstrap is an example of circular reasoning, one must remove the boot before the strap becomes a useful lifting device, otherwise it is quite circular, and self defeating as well, as one is fighting against oneself)See, you can use whatever rules you want in debate, just make sure you apply it to both sides of the debate, not just one side.
For example one I debated a guy who said “God of the Bible is evil,”
But later confessed He didn’t really believe in absolute moral truth.
But He was absolutely sure about the moral truth of God’s inherent evil.
He didn’t apply the same rule to both sides of the debate.
My favorite author once said this, and rightly so:
“Although few would admit it, our rejection of
religious and moral truth is often on volitional rather than intellectual
grounds—we just don’t want to be held accountable to any moral
standards or religious doctrine. So we blindly accept the self-defeating
truth claims of politically correct intellectuals who tell us that truth does not
exist; everything is relative; there are no absolutes; it’s all a matter of opinion;
you ought not judge; religion is about faith, not facts! Perhaps Augustine was
right when he said that we love the truth when it enlightens us, but we hate it
when it convicts us. Maybe we can’t handle the truth.

Circular and arbitrary arguments are not useful because anyone who
denies the conclusion would also deny the premise (since the
conclusion is essentially the same as the premise).
So, the argument,
“Evolution must be true because it is a fact,”
-while technically valid, is fallacious because the arguer has merely assumed
what he is trying to prove.
again we must go OUTSIDE the statement to declare it true.
Arbitrary assumptions are not to be used
in logical reasoning because we could equally well assume the exact
opposite. It would be just as legitimate to argue,
“Evolution cannot
be true because it is false.”
It should also be noted that there are certain special cases where
circular reasoning is unavoidable and not necessarily fallacious.
Remember that begging the question is not invalid; it is considered
fallacious because it is arbitrary. But what if it were not arbitrary?
There are some situations where the conclusion of an argument must be
assumed at the outset, but is not arbitrary.2 Here is an example:
Without laws of logic, we could not make an argument.
We can make an argument.
Therefore, there must be laws of logic.
This argument is perfectly reasonable, and valid. But it is subtly
circular. This argument is using a law of logic called modus tollens
to prove that there are laws of logic. So, we have tacitly assumed
what we are trying to prove. But it is absolutely unavoidable in this
case. We must use laws of logic to prove anything—even the existence
of laws of logic.
However, the above argument is not arbitrary. We do have a good reason
for assuming laws of logic, since without them we couldn’t prove
anything. And perhaps most significantly, anyone attempting to
disprove the existence of laws of logic would have to first assume
that laws of logic do exist in order to make the argument. He would
refute himself.
Most of the examples of circular reasoning used by evolutionists are
of the fallacious begging-the-question variety—they are arbitrary.
Consider the evolutionist who argues:
“The Bible cannot be correct because it says that stars were
created in a single day; but we now know that it takes millions of
years for stars to form.”
By assuming that stars form over millions of years, the critic has
taken for granted that they were not supernaturally created. He has
tacitly assumed the Bible is wrong in his attempt to argue that the
Bible is wrong; he has begged the question. Another example is:
“We know evolution must have happened, because we are here!”
This argument begs the question, since the way we got here is the very
point in question.
Watch for arguments that subtly presume (in an arbitrary way) what the
critic is attempting to prove. In particular, evolutionists will often
take for granted the assumptions of naturalism, uniformitarianism,
strict empiricism (the notion that all truth claims are answered by
observation and experimentation), and sometimes evolution itself. But,
of course, these are the very claims at issue. When an evolutionist
takes these things for granted, he is not giving a good logical reason
for his position; he is simply arbitrarily asserting his position."
