Wright was too blunt, too "rough." He didn't phrase the argument in approved left PC rhetoric and managed to expose the Messianic candidate who in reality holds the same views, but who's worked so hard to be a "non-threatening" amorphous mass of hope and change. Wright committed the unforgivable sin of brutal honesty in the land of the left.
Obama’s first book was written when he had no idea he might some day run for President. I have only looked at a few passages in the book—at least when he was in high school he seems to have had a lot of anti-white feelings. I don’t know if he portrays himself as shedding those attitudes later. If not, the book may provide useful insights into the person he is now.
