Will black bigwigs be put through the grinder like white bigwig Donald Sterling?

I doubt it.  
The "white" politically correct world encourages non-whites to batter them non-stop and at the same time batters their own community members when caught saying anything against non-whites.  How much punishment do white folks want to take for what supposedly their ancestors did long ago to non-whites? Sheesh!
Two articles below to chew on.

Richard Winchester writing at AmericanThinker:
....The NBA has banned   Los Angeles Clippers owner Donald Sterling for life, and fined him $2.5 million for allegedly making racist statements.  (Sterling’s antipathy for “people of color” has long been known, but his latest diatribe was evidently too much, even for those who previously liked his money.) 

With Sterling’s come-uppance, America has witnessed the reality that for a white person openly to express negative feelings about blacks is virtually “the kiss of death.”  As former CBS television journalist, Bernard Goldberg, observes, Sterling’s near-universal condemnation is “good news” about racism in America these days.

A white guy uttered what are perceived to be hurtful words, and the virtual roof fell in on him. 

If American society needs any more vivid demonstration of how it treats whites’ racist comments, I’m hard-pressed to know what it would be.
Did America go too far?  Subsequently, Goldberg has warned that if Sterling can suffer for racist comments made privately, others may also.

Question:  If an overwhelming majority of Americans condemn whites who make racist statements, when are we going to hold blacks to the same standard?  

Are blacks perceived to be racist?  Although polls cannot readily plumb actual racist sentiments, they can tell us if there is a perception that this or that group, or society as a whole, is racist.

A poll of American adults that was reported in Rasmussen Reports (July 3, 2013) provides helpful information.  According to this poll, 37% of American adults think “most blacks” are racists, compared to 15% who believe the same about “most whites,” and 18% who say that about “most Hispanics.” ..........

.....A Man of Sterling Character.
** NOTE: Some quoted language below may offend readers.** 

I had listened to roughly eight hours of commentary on Donald Sterling and the ugly remarks he made in conversations secretly tape-recorded by his girlfriend, before I heard anyone mention a wife. 

HE HAS A WIFE? 

At first, I thought the topic must have changed when I left the room, but no -- the TV talking heads were still discussing Sterling advising his girlfriend to stay away from blacks. 

Not only does Sterling have a wife of 50 years, but earlier this year, she sued his girlfriend, demanding the return of two Bentleys, a Ferrari, a Range Rover and a $1.8 million apartment, claiming it was bought with community property without the wife's consent. 

The fact that this 80-year-old human-manatee, married with three children, has been openly consorting with prostitutes for decades does not account for 1 percent of the media's outrage against Sterling. 

Wow. Cultural mores certainly do change. In 1947, it was a scandal when Brooklyn Dodgers manager Leo Durocher was alleged to have been having an affair with a married actress, Laraine Day. 
Durocher himself was not married, but Day, a Mormon who never smoked or drank, divorced her husband and married Durocher the day after being granted a provisional divorce decree. The divorce wasn't final, so the judge who signed the decree ordered Day and Durocher to live separately in California. (Yes, this was so long ago, the institution of marriage was still respected in California.) 

And they did. She lived with her mother in Santa Monica and Durocher moved into a nearby hotel. 
Yet and still, the Catholic Youth Organization withdrew its support for the Brooklyn Dodgers and advised its members to boycott the team as long as Durocher remained manager. 

As CYO director Rev. Vincent J. Powell explained in a letter, Durocher was not the sort of person "we want our youth to idealize and imitate," adding that the CYO could not be "officially associated with a man who presents an example in contradiction to our moral teachings."

Durocher was suspended from the Dodgers for a year, purportedly over some long-standing gambling charges. 
And that was in New York City! The reaction might have been a bit rougher in Kansas City, Mo., or Grosse Pointe, Mich. 
Today, a team owner can sit with his mistress at games, give her millions of dollars in gifts, precipitate .....
