That is so retarded.
The race of the person has absolutely nothing to do with it. Where you live has nothing to do with it. Women don't want to be approached by you. If they do, they'll let you know. This all comes back to basic social adequacy. Some girl smiling at you on the street may indicate a willingness to talk. Some girl walking fast and looking straight ahead doesn't want to talk. Learn to function as adults, and you won't face any accusations of being a creep lol.
Things to consider: what she is doing, body language, and where you are.
Waiting at the DMV? Leave her alone.
Dancing at a nightclub? Approach.
Having dinner with mutual friends? Approach.
Listening to music as she power walks to work? Leave her alone.
Not looking at you? Leave her alone.
