In my experience, most US nationals are virulently xenophobic. They believe that all the good people are fervently pro-American, and kindly extend good people the right to live. They also understand imitation is the sincerest form of flattery and feel kindly towards people who flatter them, i.e., foreigners who want to be Americans, with American culture, economics and politics. At the slightest whiff of difference or real display of independence most are extremely suspicious and contemptuous of foeigners as such. Since America is the acknowledged leader of the free world, these issues don't arise much.
The US government was furious with French resistance to and criticism of the US invasion of Iraq. The government and the conservative movement dominating it revived old cliches. Real patriots naturally hate whomever they are told to hate. As near as I can tell, they are a minority. But very, very few other US nationals regard such thinking as immoral, so the haters (yes, there really is an undercurrent of hate) are influential out of proportion to their true numbers. I hope.
