From Du Bois to Chesnutt

Dear Mr. Chestnutt,
I believe myself to be your colleague on the examination and analysis of the state of race relations in postbellum America. I read your essay "What is a White Man?" and was thoroughly intrigued by the ideas you put forth. I concur with your statement that whether or not laws regarding the status, or more appropriately, the "blackness," of mixed-race people should without question be examined and contemplated, as they are limiting and more so, are objectively unfair.
However, in my analysis and proclamation of the problems facing postbellum America I have come to the conclusion that the Negro problem has been usurped by the color line problem. It is quite interesting that your analyses of laws in several Southern states have the consensus that the color-line is drawn at 1/4 Negro blood. I researched your background as a preface to reading your work, and was astonished to find that you are 7/8 white, but are considered Negro by many other states who champion the "one-drop" rule.
I would like to thank you for your insightful analyses of what it means to be both white and black in America today, and would like to potentially collaborate with you on research projects.
Sincerely,
W.E.B. Du Bois

Questions:
(1) Du Bois asserts that the problem facing the America in the 20th century was the problem of the color-line, and in this describes the travails of the Freedmen's Bureau. He attributes the failure of the Bureau to "bad local agents, the inherent difficulties of the work, and national neglect." Upon examination, do you believe this to be true?
(2) In hindsight, how could the Freedmen's Bureau have achieved its aims despite deeply engrained racism inherent in Southern society? What would have needed to change in order for this to have happened?
(3) After reading Chesnutt's analysis on what it means to be white or black, what do you believe he thought personally on the future of race relations and identification in postbellum America?
