What way do Minny, Aibileen and Skeeter choose to help the civil rights movement?

In addition to anecdotes about rude or abusive employers, we hear stories of maids who have very close relationships with the white families for whom they work. Through her efforts to be a mouthpiece for the black maids of Jackson, Skeeter develops a close friendship with Aibileen and Minny. It's possible, through effort and understanding, to begin to heal the wounds of racism. The way in which the women expose both the good and the bad, directly relates to furthering civil rights in the Movement.
