Dear White America: I am your friend. I have written several letters of this type to you before. It pains me to have to do so again. What I am going to share in this letter may be common sense for many white brothers and sisters. Other White Americans may be surprised. Because our society is so segregated, people of color often do not have many opportunities to talk with white people in a direct way regarding our sincere worries about the problems in your community. I hope that this open letter can be part of a broader conversation in that regard...
