I can confirm this general opinion, as well. Time heals. That's a good thing. A lot of blacks today will sort of shrug if you bring the topic up, because there was a lot of racism laced throughout society, in the past. What they believe in today is more important.
Even though this was probably the biggest issue that made me decide to leave the church, back in the late 70s, through time it becomes less and less of an issue (especially) for younger African Americans. My own son doesn't have a problem with it, and he's African American, so why should I hold onto the issue? Mostly, I've let it go, though it does complicate and evolve how Mormons view their leaders, at least compared to the attitude I remember growing up with, where we sort of felt that the 2nd Coming was imminent, and we were pretty darn lucky to be in the presence of real prophets who communicated with Jesus regularly.
As a teenager I honestly had the impression that Spencer W. Kimball would go up into the Holy of Holies and have literal conversations with Jesus and/or God, in person, like Joseph Smith did. Why wouldn't they give him specific direction on a wide range of issues, especially as the 2nd Coming was getting closer and closer at hand?
Of course, over the course of my religious / spiritual evolution, I don't see things that way anymore, but I don't think the leaders of the church are fraudsters, either. I think they're doing the best they can with what they know and understand. Pretty much like a lot of other earnest religious people the world over. Which is a generally a good thing, as long as there aren't any Sword of Laban / Lafferty Brothers-type things going on.
