difference and diversity are dangerous , actually.

"The lesson here is that even in an era when we’re encouraged to learn about and appreciate cultural difference, officialdom’s acceptance of actual diversity hinges on who is doing the teaching, who is doing the learning, and whether the overarching balance of cultural power remains safely with the white mainstream.

Difference is to be studied and occasionally celebrated in the classroom, but it is above all to be managed. And when students and teachers of color begin to use education as a tool for reclaiming a suppressed heritage, they challenge the gatekeepers of cultural hegemony. And for all the talk of diversity, one thing that must never be diversified, never be shared across social boundaries, is power."
