No, black people cannot be racist - and if you try to claim they can be, you'll just get shouted down:
Students at a “safe space” at Claremont McKenna College in California shut down an Asian woman who was describing racial harassment by a black man, booing her when she declared, “black people can be racist.”She then recounted a time when she and a group of friends were walking down the street, and a black man pulled over and shouted, “go back to your home!” She said a “white lady” stopped to ask if the young women needed police assistance.“The point I’m making here is that we should not distinguish people by their race or gender or anything. Black people can be racist,” she declared, at which point a black woman holding a sign that reads “It’s too late to say sorry” approached her.“Oh no honey,” someone in the crowd said over a chorus of boos.
The lesson: when decrying racism, you are only allowed to focus on white racism. As a corollary, do not distinguish people's attitude individually, paint all people of a color with the same racism brush. You know, because that's not racist.
