I think you're over analyzing. If the pastor of your church is a Nazi, or a KKK member or something, and you heard these things said but chose to continue going to that church, it really says something about you. OK, extreme examples, but you get the idea. I believe if you tolerate racism, you're just as bad as a racist.
Putting up with a conservative pastor is one thing... putting up with "God DAMN America!" is really another, saying black and white children think differently, saying Euro-Americans are "deficient" , "America's chickens are coming home to roost", etc. I mean, I'm not offended. I've heard crazier people-and he is crazy- say crazier things, but I can see why some would be.
I never understood the concept of a "Black Church". Seems like a racist double standard to me..... I'd hate to see someone call their church a "White Church". Eek, grab some popcorn and watch [that fiasco.
