I thought that this comment by an Iraqi injured in yesterdays attacks on Shiite worshippers was interesting:
"Those infidel Wahhabis, those Osama bin Laden followers, they did this because they hate Shiites," said Sari Abdullah, a worshipper at the al-Khadimain mosque who was injured by shrapnel. "They are afraid of us. They are not Muslims. They are infidels."
Note that he doesnt blame Sunnis or Baathists, i.e., people with whom the Shiites might have to work in the new government.
