In my case, I have plenty of criticisms of my own of the US and tend to have foreign friends (in part because I grew up in a bicultural home). So I have certainly had conversations with foreigners where I agreed with some of their criticisms. And I have also had friends who lived in a country where the country as a whole had a negative view of the US and where the US had a negative view of their country and it wasn't some big personal issue between us. In some cases, it was treated more like an in-joke. In this particular case, my friend was so consistently critical in a very ugly way and so rabid about it that I did often feel like "If you think all Americans are pure evil simply for being born here, why on earth are you friends with me? How sick is that?"

This was an extremely good friend. I still miss them. One of the things that stops me from trying to reach out to them is that I don't know how to get past these issues. And I'm not interested in being someone's "whipping boy" for their personal bugaboo. I don't think there is anything healthy or constructive about something like that.
