I don’t think anything that you listed is a secret.

My dude. Really? This is the classic Mormon gaslighting; "we've always known this". No, this was actively hidden and concealed for centuries. For fuck sake, Fawn Brodie was excommunicated for publishing No Man Knows My History--officially it was apostasy--and now it's acknowledged to be historically accurate. I was in for more than two decades, and have been out for more than three, and there's a vast difference between what we were taught as being absolutely true and what was available for study when I was 20 compared to what there is now.

you sound like you have a massive chip on your shoulder

Yes. I do. I insist on things being factually true. I insist on honesty. I was raised to believe that honesty isn't just telling the truth, but that it's telling the whole truth, and not intentionally omitting truth or speaking things that are factually correct with the intent of leading a person to a false conclusion. That's what I was taught by the Mormon church, and the Mormon church has never come even close to living up to what it teaches in that respect.

A prophet can say one thing and then another prophet can say something else, and both can still be speaking the word of God authoritatively.

Yeah, no. That a bullshit rationalization that you need to tell yourself in order to be able to maintain your belief. God's doctrine is supposed to be unchanging, and yet it changes continuously. The November 2015 policy was prophecy and the will of god, and then just a couple years later it wasn't. Temple ceremonies are supposed to be directly from god, and yet those have changed massively over the years. Polygamy was supposed to be the everlasting covenant, but then it wasn't. And let me be blunt: deviating from these points of doctrine was apostasy and violators were subject to excommunication and the revocation of their temple covenants. That means that for doctrine that changed with the whim of the prophet and apostles, the eternal salvation of people was taken away.

it is the policy of the Church.

...Which is claimed to be doctrine and the will of god by the prophet, and then changes with the change in leadership.

You sound like you feel personally affronted when someone has faith in something that you can’t observe with your natural senses.

...

There are a lot of things that you can't observe directly with your natural sense. Tons of things. But you can prove their effects, and you can test them. You can form a hypothesis, you can test that hypothesis, and then you refine your hypothesis as necessary.

To be clear, if I discover that something I believe is not supported by facts, my belief changes. I follow where the evidence leads. I certainly have my own cognitive biases--that's unavoidable--but I do my best to be honest with myself, and to question my own beliefs and biases. My views have changed radically over the last 30-odd years as I've evidence that has tested and contradicted my beliefs. But what would change your belief? Would any factual evidence change them?

I am comfortable with my faith and have no interest in forcing anyone to believe like I do

Then you aren't following the guidance of the prophet for every member to be a missionary.
