When being afraid of people, isn't it more about the way they dress and act, rather than skin color?
If I am walking down the street and I see a group of young black men in slacks pulled up around there waist and a button down shirts, I am going to walk right at them with a nod and a hey. But, if I see a group of skinheads coming at me with tattoos coming out of there t-shirts, baggy pants around their groins and chained wallets, I'm crossing the street.
