"Blackface is a form of cross-dressing, in which one puts on the insignias of a sex, class, or race that stands in binary opposition to one's own. Current attention to cross-dressing, however, derives from gender and not racial studies. There are good theoretical reasons to privilege sexual over racial cross-dressing, since the construction of sexual difference is a universal feature of culture. Sexual and racial cross-dressing may not do the same work, a possibility that problematizes the use of gender cross-dressing theory to answer the question raised by race. But where the prevailing historical cross-dressing practice has been grounded on race, then the theory must do justice to the resulting sexuoracial system."
