In the Wright sermon about 9/11, the little snippet about chickens is Wright explicitly quoting from what Edward Peck, former U.S. Ambassador to Iraq and deputy director of President Reagan’s terrorism task force, said on FOX News. Wright makes very clear (if you listen the longer excerpt of the sermon) that he is profoundly distressed and saddened by the events of 9/11 and struggling, as a religious man, to interpret the event and to reflect on how our society should respond. He worries about how the slaughter of innocents on 9/11 may lead to more slaughter of other innocents.

for the story on CNN and a link to the full sermon. Gives a very different impression of Wright.

Now I have not seen the full sermons with the other offending snippets, but certainly this sermon does not convey hatred of America at all.
