"Historically, racism is equated with segregation, separating people," says Marcia Alesan Dawkins, a visiting scholar at the Center for the Study of Race and Ethnicity in America at Brown University. "In turn, we think racial progress is racial mixing. But the problem is, [that progress is] still based on appearance."

People who embody racial diversity can't be expected to explain the concept to everybody else, but their thoughts on the matter are often illuminating. As Dawkins said, "It's still important to bring issues of multiracial identity to the public's attention."
