True but there are so many factors at play that 'racial discrimination' in itself no longer has any meaning.
For instance consider:
There is nothing more painful to me … than to walk down the street and hear footsteps and start thinking about robbery, then look around and see somebody white and feel relieved. The Reverend Jesse Jackson, as quoted in US News, March 10, 1996
If you are in a neighborhood or culture in which it is mostly black people who are preying on, oppressing, bullying, threatening, raping, murdering, robbing, doing harm to other people regardless of what ethnicity or race those others are, you will feel as Jackson felt and be more suspicious of black people than white people in that environment even though most black people in that environment aren't doing the bad stuff. In a rare moment of brutal honesty, Rev. Jackson admitted that.
If you have bad experiences with black people and not with white people, you will see skin color differently than otherwise.
If you have been an employer who had a succession of difficult black employees who claimed racial persecution when you tried to give instruction or correct bad behavior and who would file racial discrimination suits if you suspended or terminated them, you quickly get to the point of not wanting to hire them at all. I have actually been in that situation having a series of new African American hires that proved to be less than stellar employees. My maintenance supervisor, a great guy who happened to be black, quietly informed me of what was going on--civil rights activists were planting these people in an effort to agitate to the point I or my supervisory staff would fire them and then they intended to file suit for racial discrimination. Thinking he was one of them, they told my maintenance supervisor. It is very difficult to extricate yourself from that sort of situation and you become suspicious of anybody with black skin who applies for work.
Does racial prejudice exist? Of course it does. But the civil rights do-gooders did the black community absolutely no favors when they starting demanding special treatment and special protections for black workers. Or when everybody has to walk on eggs around black people lest they be accused of some offense like saying a wrong word or phrase they would normally say or bringing watermelon to the company potluck dinner. Employers just trying to make a living and keep a business healthy and who want a cohesive workforce that gets along with each other just doesn't want to have to deal with that.
Wherever people are allowed to just be people and there is no militant racism nonsense being pushed, black employees are doing just fine and are loved and appreciated and promoted as much as anybody else.
