Doctrinal Reasons for leaving

They're always convinced that we're leaving to 'sin', and while that may be a bonus, for most of us that wasn't what started our exit:
Here's the big crack for me that opened the chasm and allowed me to look at things objectively:

My #1 Issue - “By this ye may know if a man repenteth of his sins—behold, he will confess them and forsake them.” (D&C 58:43.)
The Church does not live up to this incredibly simple doctrine that was hammered into my psyche from as early as I can remember.
If the church as an organization will not openly confess when they have done wrong & forsake that behavior, then "amen to the priesthood or authority of that [church]."
I had been having that feeling about many things, most notably black people & the priesthood, but the 2019 SEC scandal and the fact that active members of the church have ZERO idea that anything nefarious happened at all? That's not confessing & forsaking. That's forsaking (somehow I still doubt its actually changed) when you found out you'd been caught with your hand in the cookie jar for decades. Every choice the leadership of the church made going back to the beginning has been rewritten and reinterpereted, whitewashed, etc. The whole thing is a fraud. Got off my mission in 2000 and it was about then that they renamed Ricks College BYU Idaho. And BY always struck me as a racist. 21st century and they were rebranding something after a racist. Sat on my shelf for another 19 years or so.
And everything else fell apart once I looked under the hood to see what was powering the engine of the good ship zion.
