I would give this article a little more respect if it said 'all people' rather than 'white people'. It would seem that the author believes that only white people are capable of racism and prejudice. 
Black Lives Matter is prejudiced. They hijacked the Toronto Pride parade 2 years in a row! They care about no one but black people, but white people are encouraged to support them? They are just causing mayhem like the white supremacists or the jihadist terrorists. Sure they don't have the disgusting history, but they have to start somewhere. All these groups are steeped in hate. They all suck.
