What were the key points raised by DuBois in his criticism of Washington

"The most influential public critique of Booker T. Washington’s policy of racial accommodation and gradualism came in 1903 when black leader and intellectual W.E.B. DuBois published an essay in his collection The Souls of Black Folk with the title “Of Mr. Booker T. Washington and Others.” DuBois rejected Washington’s willingness to avoid rocking the racial boat, calling instead for political power, insistence on civil rights, and the higher education of Negro youth."
