Would any black person walk(ing) in a white neighbourhood at night reach home before being racially abused or attacked? I assume, thomasm and Steven, that you are comfortable with this generalization? 
To 'strive for a united nationality...' begins with small things such as you both having to recognize your tone. I was also hoping you would stand up to Les Eberhardt who insists that every neighbourhood (whatever that means) inhabited by black people is a violent cesspool.
However, if that is the attitude you have about how black people live, then it should come as no surprise that as racial groups our paths are diverging.
