Yup, it's just an old liberal argument to try to pour cold water on an American who loves America. Just try to compare the America loving American to Hitler and silence his "USA, USA" chants. They've often tried to compare Reagan to Hitler. Sad to see some Freepers have started using that old liberal technique.
The comparison is Putin to Hitler and only in the sense that both claimed to be nationalist. No Freeper I know has compared Bush to Hitler.
