Focus on the similarities not the differences
It would be nice if all people would accept others and didn't focus on the differences. In my experience, there is a widespread xenophobia in our society, because of fear and ignorance. This must be corrected before it gets worse. As teachers, we are obliged to do something as soon as we suspect racist tendencies among students. It is not easy to act on this, because some things are so subtle. Our school is located in the countryside in a rather small community, and its xenophobic tendencies often come from home. On the surface they may seem innocent, but it's scary to think about the potential consequences that could come of it.
