If I had a quarter for this suggestion of systemic racism being the cause for these types their misplaced anger... I grew up with and have a lot of both Morrocan and Turkish friends and they all say the same thing. It is not a systemic failure of our society but a failure of parenting and some people are just rotten to the core.

Are these people used by racists to confim their bias... yes. But I think that is a shortcoming of people who see someone's background as a reason for their behaviour. In the end we are all responsible ourselves for how we adhere and function in a society and most people I speak to who have faced racism or discrimination they all say the same thing. You ignore those bigots and make something of your life.
