An important historical document.
In a way, it's only natural that cultural change takes a long while. There are plenty enough historical examples of change and improvement as a generational process. On the other, how can you tell the oppressed they must wait, and keep a clear conscious? How can you say it will get better, but ask them to pay a price of ten or twenty years more of steady humiliation and anxiety living in the shadow of violence from neighbors and the law enforcement community?
History and change. Neither are easy.
