You know, I'd bet dollars to donuts (I know it's even money now, but the expression used to mean "I'd give big odds") that most of the time that pastor talks about Jesus, and brotherhood, and all the stuff you'd hear in any Christian church in America, and that every now and then he goes a little over the top to make a point, and the congregation takes it in stride because that's the way he is.
I've seen the clips, but I don't think that those clips represent what happens in that church on a typical Sunday.
I just don't believe that his run of the mill Sunday Sermon is a racist hate message. If it was, then I think a politically savvy guy like Barack Obama would have split a long time ago.
It just doesn't make sense any other way............
And after listening to Obama's speech on the subject, I can't find any fault with Obama.
I grew up in an America where people told nigger jokes and spic jokes and polack jokes and guinea jokes, and felt very comfortable doing so as long as the targeted minority was not present in the group, racism was a part of the American culture. A twisted evil part of the culture, to be sure.
but as Solzhenitsyn wrote

"Wouldn't it be wonderful, to take all the evil people and put them over there, then we wouldn't have to deal with them. And all of us good people would stay right here. The problem is that the line separating good and evil cuts right through the human heart. And who can cut out their own heart?"
