During the years 1890 to 1920 black communities and business districts were burned down by white mobs from Tulsa to Rosewood. All the hard work in the world is meaningless (as the Jew of Andalusia and Central Europe learned) if you do not have the most basic right of citizenship. The right to the physical protection of the law.
Although I applaud your zeal, your response is a non-sequiter. Rev. Peterson posits a scenario where blacks build their community up instead of tearing themselves down, and the result would have been a proud and equal black community instead of the race-baiting self-identified "victims."
Racial healing was and is possible. But not if it comes from a position of guilt-mongering.
Peterson argues that if blacks were perfect enough Jim Crow would have just evaporated. That is nonsensical.
Black conservatives come in two flavors. Those who seek to build a base of support within the black community and those who simply flatter white people. The flattering white people approach will get access to white checkbooks but it will end up in a Alan Keyes, Roy Innis, Joe Clark dead end when whites figure out that they are wasting their money on a loser.
The "blacks brought Jim Crow on themselves because they aren't perfect and if they had been perfect white people would have had to love them" argument is fawning flattery.
