In the end only kindness matters...

Yes, most of the time. I walked in the neighborhood with other Americans late at night, and by myself during the day. I didn't feel threatened, or hear any anti-American sentiments. However, I was there during a relatively peaceful time. Perhaps things would be more contentious during war/bombing times. The recent conflict started only a few days after we left. It's the same as anywhere, you just have to be aware of your surroundings and not behave as a fool or disrespect the locals. This avoids a lot of problems. :)
