The Forum Council did not oversell its claim. The Du Bois-Stoddard debate turned out to be a singular event, as important in its way as Lincoln-Douglas or Kennedy-Nixon.

B.] Du Bois, who could not accept their inferior status, were the chief cause of racial unrest in the United States, and he looked forward to their dying out.
