When feminism does not explicitly oppose racism, and when antiracism does not incorporate opposition to patriarchy, race and gender politics often end up being antagonistic to each other and both interests lose.
Racism is when you have laws set up, systematically put in a way to keep people from advancing, to stop the advancement of a people. Black people have never had the power to enforce racism, and so this is something that white America is going to have to work out themselves. If they decide they want to stop it, curtail it, or to do the right thing ... then it will be done, but not until then.
(Spike Lee (b. 1956), U.S. filmmaker. Interview in Roger Ebert's Home Movie Companion (1990).)
Since the small racists are innumerable, sometimes we need the big racists to attack or destroy the small racists, in order to end racism everywhere. As a matter of fact, the big racists will inevitably taste and swallow their own medicine. This is the big fish, small fish theory. Remember George Corley Wallace Jr., the former Governor of Alabama, during the Civil Rights Movement of the 60'S.
