America has freedom of speech in its constitution, but doesn't give a damn about it.
And Americans infringe the right of people to express their religion just as much as a french law. Anybody coming to school in a turban in America would be beaten to a bloody pulp. Homosexuals would have something very similar happen to them.
America's rights of free speech (and so on) have always seemed paradoxical to me, or at least had bad side effects- for example, like you said, you could come in with a turban, but get badly bullied.
Sometimes being a little more uptight, for example in England (yes, I'm blabbing on about there again), can have nicer results than going the whole way.
There is plenty of infrastructure left. When troops were going in through cities instead of doing the usual destroying of essentials (power, water, etc.) All of it was kept in working order. Troops who had no prior experience were even doing what most people would consider menial jobs as the people who had done them prior were all Saddam supporters and left before troops got there (Plumbers, electricians, etc.)
And sure, Iraqis were killed, The insurgents running around shooting at troops. Sure there were some civilian casualties, but name any substantial offensive military action that didn't have any. There is also the difference from genocide and casualties of war. Under saddam people killed by the hundreds for seemingly no reason, the number of mass-graves (and the number of bodies in them) proove that.
A lot is being done to improve the conditions there aswell. Sure its not going to look like 5th Ave. in Manhatten, but they are all getting things they never had before. Well built 'modern' structures, entertainment/recreation centers, indoor plumbing, where available electricity. How better living conditions is bad for anyone I fail to see.
What it comes down to no matter what your feelings about it now are; Only time will tell. If it works out well, then great. If it doesn't, did it turn out better than what probably would have happened if Saddam were still in power?
