Barack Obama has publicly denounced the racist, hate-mongering comments of his black-power-and-liberation-theology-spouting pastor. According to Obama, he did not know that Rev. Wright believed these things, and claims that if he had heard a sermon such as the ones circulating the media, he would have felt very uncomfortable at the church. This tells us something about Obama.
A. Obama is incredibly dense and after 20 years of devotion to the church and pastor, remained genuinely in the dark about the passionate tirades frequently given by Rev. Wright.
B. The Obama and Jeremiah Wright love fest was a "marriage of convenience" to assure the American public that Obama was indeed a Christian, and Obama either never or rarely attended the church.
C. Obama was fully aware of Jeremiah's radical bombasts, and now that they have surfaced in public, is attempting to plead ignorance in order to remain the "sugar pill of hope" for America. Obama is, after all, the same man who refused to wear a flag pin after 9/11, and who refuses to put his hand over his heart during the National Anthem or the Pledge of Allegiance.
We may never know. However, we can conclude that Obama is either devoid of discernment and/or perceptiveness (bad for a president), slept through all of Jeremiah Wright's sermons (this also does not bode well; presidents need attention spans), or is a slick and highly deceptive politician (code for blatant liar).
