Why did Stanton use the Declaration of Independence as the structural and ideological model for the Declaration of Sentiments? How were Stanton's arguments related to the interests and experiences of middle-class women? In 1870 the Fifteenth Amendment to the U.S. Constitution prohibited states from denying the vote to black men; in 1920 the Nineteenth Amendment prohibited states from denying the vote to women. In you opinion, why did gender discrimination last fifty years longer in this arena than did racial discrimination?
