In chapter 14 of up from slavery why did this speech of September 18 1895 at the Atlanta Exposition become a historical touchstone that separates black activism from black moderation?

In Chapter 14 of "Up from Slavery," Booker T. Washington's speech at the Atlanta Exposition on September 18, 1895, became a historical touchstone because it articulated a philosophy of accommodation and gradualism for African Americans in the face of systemic racism. Washington advocated for vocational education and economic self-reliance, emphasizing the importance of building relationships with white Americans. This approach contrasted sharply with the more militant activism championed by figures like W.E.B. Du Bois, who called for immediate civil rights and political action. As a result, Washington's speech marked a significant division between those advocating for integration and civil rights versus those promoting a more moderate, gradual path to equality.
