I even dealt with some of that. In colorado in 8th grade (1992) my science teacher essentially asked how we thought differences in race came to be (skin tone etc). I don't think he was expecting my answer. I with complete innocence thought to myself, I am not ashamed of the Gospel of Jesus Christ, I can't believe these people don't know the answer to this, so i will answer.

So I rose my hand and explained as best I could the story of Cain and Abel and later egyptus and ham, etc etc. That was my explanation for black people. (I had a book of Mormon explanation for native americans which branched off into Polynesians, Etc that i didn't give. I wasn't sure about all the races, I thought maybe it was something similar.)

A black girl who sat right behind me (but was actually a full blown woman at that point already while I was a very late bloomer) said, what? I turned around in my seat and said, you really didn't know that? She slapped me right in my face as hard as she could. My teacher tried to do damage control as best he could. To say I was embarrassed would be a major understatement. Took a long time to live that one down. So I guess I wasn't quite born late enough actually:)

My dad, who turns 88 in October, gave me the book Mormonism and the Negro when I told him about my story from above and started asking questions. I read the whole thing including my dad's underlining and marking and notes in the margins. I nervously told him that I had an uneasy feeling the whole time I read it. He told me that I was on a slippery slope since most all of it was just quotes from Prophets. That makes my dad sound bad but he is great actually.

I went to Baltimore on my mission and when leadership would come in and address us they would just tell us to tell the investigators that we don't know the why about any of this stuff. It caused quite a bit of consternation with some of the members and a lot of the investigators in my time there. Maybe it's not as big of a deal there now since more time has passed.

In 2013 when the church came out with it's essay on the topic, I decided I was going to figure this whole thing out:-) I basically became an expert on it in my mind.:)

My dad and brothers and I still discuss it from time to time. I just ordered him the book Second Class Saints. My uncle was the athletic director at CSU Pueblo and knows the professor there that wrote it. Says he's a really nice guy.
