Watch this clip of a show called "The Democracy Club" to see a Saddamist (I presume) telling an Iraqi Shiite that he'll cut his tongue out if he talks about Saddam. The Iraqi Shiite replies with "eat shit, I WILL talk about Saddam". They get up, the Saddamist starts throwing punches and a fight ensues. You can hear the Saddamist yelling obscenities, insulting the Shiite's father and calling him a Shroogi, an Iranian. The Shiite replies with some of the same pejoratives ("no YOU are despicable!").
This is an example of why democracy and reconciliation have been so very difficult in Iraq.
