Is there one particular race who are more often victims of persecution in comparison to others?

I had an interesting conversation with a fellow Irish person. He was arguing that black people are just as racist as (sometimes more racist than) white people. Then he brought up the argument that white Europeans have been put through slavery for a much longer period in comparison to black people.

So I wonder… In terms of how racial equality and discrimination is in the twenty first century. Is there any one race that tends to be victimised?
