What are the three supplemental truths that Du Bois said must never be lost sight of?

W.E.B. Du Bois emphasized three supplemental truths that must never be overlooked: first, the importance of recognizing the historical and systemic nature of racial oppression; second, the need for a strong and educated Black leadership to guide the community; and third, the understanding that the struggle for civil rights is intrinsically linked to broader social justice issues. These truths highlight the complexities of racial inequality and the necessity of a multifaceted approach to achieving true equality and justice.
