They are hypocrites, and actually are unaware of it. Their blind hatred of their own country puts any other act by any other person or power around the sight that they can view with their own blinders.
99% of the middle east is arab land, arab people, yet they blame Israel for the lot of the "poor palestinians", while not questioning the rich oil states, who have the land and resources to lift these people out of poverty if they chose to do so.
It is racism and cultural relativism pure and simple.
In their heart of hearts, I think these folks would admit that Saddam, Arafat, Bin Laden are worse than the things they would ascribe to Bush. They however, think they need to shield the dirty ignorant masses, who murder, torture, subjugate women, etc... because they are too backwards to know any better.
This kind of thinking has infested the left and poisoned it rotten to the core. You can only look at the paternalism that these people show towards racial and ethnic minorities in our own country to know this is true.
These granola white bread volvo driving types truly believe that blacks, browns are inferior and that without their protection, they would get swallowed up in a system that put everybody in an equal footing. If I was an intellectually honest latino, black, or arab, I would be ultimately offended with the crowd who is coming out to "defend them".
