Request for resources

[riot_nrrrd]

So... I'm working through the race and ethnicity chapter with my students at the mo', and predictably, several of the white students are turning in reaction papers to me that talk about the evils of "reverse" discrimination. I know that, once upon a time, I read a pretty excellent essay on the term(s) "reverse discrimination"/"reverse racism," and why these terms are egregious and offensive warpings of the way discrimination and racism actually work. But I cannot, for the life of me, remember what it is I read; and an Intarwebz search for the term "reverse discrimination" reveals any number of resources that take the term at face value. Help, anyone?
