It's tough for some of us to understand and interpret what Dr. Jeremiah Wright is talking about, when it comes to politics and prophecy, especially if we're white and live in a white-dominated society. His words, whether inspirational or alienating (or even strange) are the words he speaks in a different setting. Couple this automatic misunderstanding with our inherent racism against anything that challenges white folk's sense of the status quo, and you get words spoken out of context and almost nearly impossible to understand.
Diana Butler Bass writes a very clear post about understanding Dr. Wright in a way that doesn't diminish him; rather it beckons us to understand the nature and style of African-American preaching that has at its root the oppressive nature of slavery and a reaction to white America's inherent racism.
To me, she explains it far better than I ever could.
