I wouldn't say I'm exactly proud to be an American ... but ...
Ouch
I have to say, that's rather inflammatory. I'll be the first to admit that Americans in general aren't the coolest of people, but that was just harsh.
Just like any culture, you can't just put a blanket label over everyone in America and say, "Well this is the way THEY are."
There's also really good Americans, just like there's really bad people in other countries. Just because our government does something doesn't mean that all Americans support it, just like you probably don't support all the policies of your own government. You only need a bit more than half to make a majority, after all.
