What unites American women today?

From the Washington Post: "A mass movement requires a clear goal, compelling enough to unite people across the dividing lines of race, class, age, religion, sexual orientation and ethnicity, and to persuade them to work collectively to achieve it.… But what goal unites American women now? Which leaders inspire us? As Justice Ruth Bader Ginsburg recently said, women's autonomy and dignity in the United States are being undermined and eroded just when gay rights are getting overdue attention and respect. Feminism unfinished, American women's movement finished, would be a sad epitaph to a glorious history."
