American Sniper appeals to the patriotism of the average American - which is exactly what angers you of the left.
What angers me is the fact a racist hater like Chris Kyle is elevated to the status of hero because he's good at killing women and kids.
Yes, it looks like he was racist. It also looks like he was barely in control of his actions. But he was a victim too.
Chris Kyle's life was stolen from him by the US military long before another ruined man shot him.
So many soldiers come home unable to function. We read in the news of some becoming mass shooters or have killed only their family members. In order to be able to kill women and children (and men) in a country that never did anything to deserve it, the military teaches them to kill their own compassion, their very humanity.
American Sniper is not about patriotism. Its about one man's ruined life, wrapped in a flag to appeal to the knee jerk element who can't think for themselves.
