Dr. J,
I think you might be missing a valid point in all of your way too P.C. objections to this whole thing: maybe it's a largely black/white community. If I'm this guy, and I don't see too many (if any) asians, arabs or hispanics in my community, why am I going to extend an offer to them? People are dissecting this way too much. This is my take on it...
Head of church sees large community, healthy church community and wants to bring more whites into his church to worship. This is healthy on numerous levels.
1) No matter what, it brings people together. Let's face it, whites are going to show up because they're being welcomed. Very few people will go out of their way for $5, especially if they're not comfortable in the situation. So, if they're showing up, they were more than likely thinking about attending a church, or the publicity behind the stunt got them thinking about it.
2) Even if someone does take the money, it gets them in the door. This guy is doing this because he wants people to hear his message. If they're in the church, they'll hear it. They might not listen to it, but they'll hear it.
3) Curious whites who might be uneasy going into a black neighborhood for once get a chance to see the black community for what it is. A community of black people. Not a community of thugs, rapists and drug dealers. If this gamble pays off, we could see a huge boost in race relations in a place, almost 50 years after the start of the civil rights movement, that still needs help in this regard.
Quit trying to break this down with all sorts of doomsday what ifs, and have some faith in humankind for once. All of this liberal think the worst of everything so the government can create another program crap has got to go. I wish this guy the best.
