I would bet that I know some of those people from both churches. I lived in Omaha during the early 80s and played bass with a local gospel band. The leader was a DJ of the local Christian radio station and we played almost every church in that area. That's a nice story.

The reason the churches for the most part are not integrated is because the neighborhoods are not integrated. You can't force people. They will do it on their own. Look at the fiasco of forced school busing. No one was happy, black or white. I know. I also drove school bus in Omaha and drove the black kids out to the white suburbs. They were not happy.
