This is sad to read. People of every race--black, white, whatever--need to make an effort to get to know their neighbors. Simply saying hello to people when you're walking, introducing yourself, pointing out where you live, telling them about your pets, children, where you work or go to school, where you moved from, etc., can make a big difference in a community. I used to live in a very racially diverse apartment complex (more than 50% non-white). I was friendly with everyone and felt like the people I got to know were almost friends. Smiling, waving or saying hello to people forms a small bond that could help these overzealous people realize that if they reach out, they will see that they are over-reacting. By being friendly and getting to know people, we can learn that most people are not threats to us, and we can all be united in watching against the people who really are.
