This is an interesting phenomenon.....at least from my personal perspective.
When I was a kid, growing up in a small town in the middle of Missouri, there were two Baptist Churches, one white and one black.......today, there are STILL two Baptist Churches, one predominately white, and the other predominately black......
Now I know, since I belong to that church, that blacks are more than welcome in the predominately white church, in fact the two share choirs and vocalists on special Chjristian holidays, and occasionally the two pastors switch churches for a Sunday or two......however, there remains two churches, and they remain segregated to an large extent. I suspect that this has much more to do with common values and "community" than it does with racism......
What's missing from the study is a "solution".......I'm surprised that they don't propose "affirmative action" quotas, mandated by the government for church membership......
