How do we learn prejudice? Social scientists believe children begin to acquire prejudices and stereotypes as toddlers. Studies have found that school teachers clearly telegraph prejudices, so much so that some researchers believe children of color and white children in the same classroom effectively receive different educations. In the case of police, bias may affect split-second, life-or-death decisions. Shootings of black men incorrectly thought to be holding guns— George Floyed's murder and many more racial hate crimes displays stereotypes of immigrant in New York, police misconduct —brought this issue into the public debate. We refuse explicit bigotry. Cruelty, bullying, and slurs are just not OK in school.
