I lived in a plenty tough neighborhood. When somebody called me a 'dirty little Guinea', there was only one thing to do-break his head. When I got older, I realized that you shouldn't do it that way. I realized that you've got to do it through education. Children are not to blame. It is the parents. How can a child know whether his playmate is an Italian, a Jew or Irish, unless the parents have discussed it in the privacy of their homes.
