"It's general advice that, with a few modifications, can be applied to any person regardless of race. It can be applied to one person or millions."
Sort of. By giving the suggestion, that clearly indicates you see the suggestion as significant.
No, I could clearly see by the tone of your post where you were going with your questions. To me the suggestions weren't significant, they were typical. I saw Coleman Young and now, Kwami Kilpatrick do it as mayors of Detroit for almost 30 years. Instead of addressing the problem it gets buried while putting the person asking the question on the defensive.
I grew up in Hamtramck which is a very small but highly racially mixed city surrounded on all 4 sides by Detroit. I did 3 years as a substitute teacher in the Detroit and Hamtramck public school systems. The things I pointed out where problems that I saw with my own eyes. I don't need any charts, surveys or reports to tell me what I witnessed on a daily basis.
