That ad is excellent.
From what I know of the prop 8 voter breakdown, young blacks were much more accepting of marriage equality than older blacks. I think the gap was more generational than racial, even if blacks were less likely on average to support civil rights.
I have no sympathy for the Mormons though - who should know better than to use the government to force their views on others, after the way they were treated in the 19th century. Unless, of course, they are willing to begin paying taxes like other religious organizations which endorse, actively recruit supporters for, and heavily fund political campaigns.
