CyberAnt, that is just not true. There are only two people that I know of who are saying he approved of President Bush and the war. Both have a reason to hide the truth. Meanwhile, his brother and people who knew him in Norman Oklahoma (where he "coincidentally" met the would-be 9/11 terrorist and gave/lent him his email password) indicate otherwise.
Consider: if his father put him in touch with Michael Moore for a job that ended with his horrible death, there's a guilt-thing at work here, plus reason to cover his backside.
I've only read about the father and the Hollinger (?), the supposed partner, say that; and I wonder if Hollinger didn't get that from the father.
double-agent perhaps?...a friend of the enemy.
