Bigots in Boston?

According to Fox News:

• The "anti-racist education" program in place at Newton Public Schools in Newton, Mass., a wealthy, liberal niche of the Bay State, has angered some parents who believe the school district is more concerned about political correctness than teaching math skills.
  
  According to benchmarks for middle school education, the top objective for the district's math teachers is to teach "respect for human differences." The objective is for students to "live out the system-wide core value of 'respect for human differences' by demonstrating anti-racist/anti-bias behaviors."

I'm very confused. I thought racism only existed in Alabama and Texas. How did this come to be a problem in the Boston area?
