The "Washington" in this question, of course, is Booker T. Washington, an African-American leader. Washington advocated gradualism. That meant being patient and doing what white society would allow, which meant changes and better times for blacks would come slowly.
A different point of view was taken by another leader in the black community: W.E.B. DuBois. Dubois noted that Washington's approach was not accomplishing any real gains for blacks. He also felt that Washington's point of view showed acceptance of the racial inferiority of blacks. Plus he saw that institutions in the black community were being dominated by persons like Washington, rather than really empowering all individuals for themselves.
DuBois argued that all black citizens should have the right to vote, equality as citizens, and access to education according to their abilities.

The most important reason for the collapse of Rome was the failure to actually integrate what they conquered. When Roman soldiers conquered new lands, it was rare that they ever attempted to force their culture, ideals, or laws upon the natives and barbarians. Thus, when the Empire began suffering internal struggles, the natives they had conquered decided to take action, which lead to the swift collapse by barbarian invasion from all sides. It's hard to pick a LEAST important reason, seeing that there were many of them, but I suppose a contender would most likely be the common refusal of the Empire to even acknowledge that barbarians were rising. On the outer edges of their territory, in places like Gaul and Morocco, the Roman government was reluctant to even recognize the threat of the barbarians, thinking that even accepting that these barbarians were causing trouble would weaken their prestige in the public eye.
