The "naive" one has returned. (me)
After re-reading this thread and particulary Azizi's opening post, I find no problem with the discussion.
What I do find interesting is the constant reference to "Whites" saying things that are offensive to "Blacks". I was in Elementary school grades with Black kids, on to High School and College and did not pay attention to ethnicity, only how we treated one another.

I don't understand Boberts speaking "Slave Talk" as I did not grow up in the 1800 hundreds. I have some black aquaintances and friends but not because I talk and act like them (I am White) We do "the handshake" because they instigate it and I consider that a honor. I am still very clumsy at it. NOT with it but at it.

To my point - the reference of White making negative comments that may offend Blacks is overshawdowed in my surroundings by the comments that Black politicians make about other Black politicians. I bring up the political aspect as it is the only negativity I experience.
Examples;

A councilwoman in Detriot emceeing a "roast" that named the Black Mayor "Sambo sellout of the year."

Maryland Repub. Lt. Governor Steele, candidate for the US Sentate, being pelted with Oreos the past couple years. By Blacks, he is Black.

In Ohio, Sec. Of State Blackwell being called "Whitewell" by Al Sharpton. Blackwell is Black.

In the case of Steele (Maryland) A Black Democratic blogger refers to Steele as "Simple Sambo" and caricatured him in minstrel makeup with the caption "I's Simple Sambo and I's running for the Big House."
Marlyland State Sen. Lisa Gladden, a Black Democrat, defends the attacks on Steele as "Party trumps Race."

The above is my secondhand experience with racial overtones. I have not had any firsthand experience that I can remember over the past 30 years.
Comments, Azizi? Asked for in a very humble way although perhaps a naive way.
