That may not work with little kids who just saw their father murdered. It may take years for them to learn that evil exists in every race.
I've also lived in Indian Villages where I was the only White Boy, reverse racism of sorts and it does one good, being the hated minority for a year or so. I would never view Indians in a negative light, because I began to see the good in their society too; understand their culture. It was a good experience.
Depends upon how they are taught
