It all depends on how you approach the situation. I think it is because they are rude. I am black and live in a black neighborhood. I hate it. I don't think they are singling you out because you are white.
Rude people expect everyone to bow down to their agenda, regardless of their race.
My guess is they have little or no home training or respect for others. I don't believe their behavior stems from being African American, just being poorly raised by their families. I feel this is rudeness, and that it is another major problem in the black community that cannot be pointed out without being pilloried as a racist. This behavior is a manifestation of powerlessness. I didn't invent this term.
