The parents of an 11-year-old biracial boy in Center Line are angry after the middle school student was referred to by a teacher as "a mutt."

Kaden Brown tells WJBK that students in the Language Arts class at Wolfe Middle School were doing their work, when the teacher made the comments.

"... and she said I have beautiful curls, and she asked if I'm a mutt. And I asked, 'What does that mean?' She said, 'That means if you're mixed with a whole bunch of different races.'"

Kaleb has since posed with a sign that reads, "I am not a Mutt," and the picture has gone viral on social media.

The boy's father, Kevin Brown, tells the TV station his son is the victim of a specific type of racism that is often overlooked.

"One of the issues that we really need to discuss is how biracial people are treated. They're not black enough for black people, and they're not white enough for white people. So now they're feeling left alone." He went on to say, "They have a void within themselves that needs to be filled. And it's not right that my son has to deal with an issue like this so early."
