I address this in my book Vexy Thing: On Gender and Liberation. Both the gender liberation and civil rights movements were struggles to make society more open, fair and just. But both movements tended to advantage those who were already relatively advantaged within the oppressed category. So, at times, the racial justice movement advances the advantages of elite African Americans and the feminist movements prioritizes concerns of upper-class white women. That tendency is an appropriate source of tension and conflict, in academic circles and in the political world, writ large.
