To celebrate the highly-anticipated book Notorious R.B.G.: The Life and Times of Ruth Bader Ginsburg, and to honor the feminist and legal pioneer, leaders, activists and influencers such as Wendy Davis, Lena Dunham, Chirlane McCray, Janet Mock and others tell us why they dissent, and why it matters.

Join the campaign by posting “why you dissent” using the hastags #IDissent and #NotoriousRBG.
