Of course blacks kill black, whites kill whites too.  Murder knows no color.

Affirmative action was the most purposefull way to move the most qualified black students, or worker, into a position of opportunity.  Some did very well, some did not.

Show me facts that a white person was deprived of work or college.   A white guy with marginal scores didn't get to Stanford, poor baby, he has the rest of the nation to chose from.   It's a false narrative to say opportunity for a black person means a loss for a white person.   It does provide an excuse for the angry marginal white applicant that doesn't get the job or college admission.

Let me know when you can prove facts and not try to claim your opinion as such.
