I can't comment on this specific story because I have not followed it closely.
I believe that if the groups of people that cry racism would spend 1/2 of the amount of time, effort and money (that they spend crying) on education of their children and the people close to their community, it would be the first stepping stone in reducing racism.
I am not Jewish, but I believe the Jewish community handles racism far better than other groups. When someone paints swastikas on one of their buildings they don't sit around crying. They rally the community and go back to historic teachings.
They often talk about the holocaust, and why shouldn't they, it is an important thing to reflect on.
Bottom line is:
If you don't teach people the wrongs that have happened in history, then they will repeat themselves.
Education and not brainwashing will go along way in solving this issue.
my 2 pennies if it makes any sense
