Read the post under yours. If you use a cheap excuse like what you just said, anyone on Earth can be a xenophobe. It makes no sense. All it is is Americans thinking about the country they've been surrounded by their whole lives.
By your own logic, you'd be guilty of this too. Isn't it narrow to assume a simple human habit is completely related to heartless offense? How many people have you offended by making assumptions about them?
You can't "blame" anybody for being influenced by their surroundings. I am positive most foreign awards ceremonies value their own country's films more as well. That's not xenophobia. In fact, that's closer to patriotism. And suddenly it's evil when it's American?
