While what you say would make perfect sense if dealing with people without mental issues, in fact many people have a mental disorder that among other things affects them on this subject.
Seriously, there are places such as universities that teach that BY DEFINITION racism is a phenomenon only existing in whites. I recall a news story not long ago about a university that not only taught this in classes, but had an indoctrination program (of course it was not called that) where dormitory residents were counseled in this and expected to agree with it.
Of course that is insane. But there are people dedicated to insane propositions.
I assure you that bizarre as it sounds, there are people -- both white and black as well as probably other races -- who absolutely do believe no act or thought of a black person is ever racist. No evidence can persuade them to the contrary. It is part of their (mentally-disordered) belief system.
We could go on FOREVER talking about all the individual bullshit that people believe. I'm right along with you if there is someone who actually believes that anyone is "not" capable of being racist and/or a hate mongerer.
However, I also don't support that there has been some great "paradigm shift" of rampant, institutionalized racism that is denying white males of their fundamental rights and freedoms, OR of gainful employment.
Has there been, and will there be, real stories of discrimination and racism against whites?
You bet there is...
But it's all a sad reality of the human condition, independent of what race you are.
From the CNN page linked above - Black Panther chairman thanks Obama by name for dropping the case...
"UPDATE: Malik Shabaaz, chairman of the New Black Panther Party for Self-Defense, told CNN Friday that Samir Shabaaz is no longer a member of the organization, and that his organization does not support voter intimidation.
"We want to thank President Obama and his administration for dropping charges against us that were vindictively brought by the Bush administration," Malik Shabaaz told CNN. "We don't condone any type of illegal activity at polling stations."
Shabaaz said the members in Pennsylvania were not acting under the direction of the national party."
