The United Methodist Church is a white church. They might grudgingly let a few blacks attend and accept donations from gays but they are as bigoted as the Baptists.
The AME(African Methodist Episcopal) Church is a whole different(darker) ball of yarn.(they separated in 1816)
I don't think churches in America are as integrated as some other facets of life, like schools and water fountains....I could be wrong...I'm a white pagan and know nothing of black culture or christianity.
I'd be willing to go out on a limb and say that I bet the AME never even held a vote of that sort.
