Protestantism survived slavery. Not only that, but African American christians are some of teh most devout ever. Adaption, change, it happens. Slowly, but they will not empty out.
They change by omission. Keep it strong enough to keep the old in, but quite enough on some issues to allow the youth leg room for their beliefs. Adam-God, Black man's curse, evolution, contraception, republican politics, and even caffeine, all different now.
You just have to get a newer, fresher narrative. Christianity just said, well the southern slavery baptists understood Jesus wrong, try out new and improved recepie! What they don't realize, there isn't any secret Jesus recipe, it bullshit.
Same with Mormonism. They keep quite for a few years, read the scriptures differently, get a new narrative, and trudge along. If Christianity survived the Crusades, child abuse, slavery, abuse of women, war, etc for a thousand years without emptying out, then Mormonism won't be any different.
