Is discrimination a problem for teens?

I think the worst thing a human can do is discriminate a person based on assumptions and characteristic traits. Everyone is special and unique but that doesn't mean to prosecute them because of this. I see this happen all over school. What teens and young adults need to realize is that you do not need to except the person and love them but to have and to show tolerance. Which simply means you don't have to like the individual but just coexist with them. Today's  discrimination is to very different to prejudice ideals dealing with race or sexuality, this has more to do with what type of people you hang out and the status you have at school. I myself is accused with committing this act so I am here to ask how to gain better understanding of  differences other people may have.
