3. In what way does disenfranchisement make America "a liar", according to DuBois?

America calls itself a democracy but takes away the right to vote for some of its citizens.

Explanation:

A series of laws, new constitutions and those deliberate actions that prevented the black citizens from voting came to be known as Disenfranchisement. This Disenfranchisement took place in the years following the end of the Reconstruction Era. The first measure of Disenfranchisement was observed from Oklahoma following its statehood in the year 1907.

On these measures W. E. B. Du Bois, who emerged as the spokesperson for his race argued that though the United States calls itself a democracy, it takes away the right to vote for some of its citizens.
