Last tuesday after work I went to Walmart. While I was looking at shoes I heard a very loud, obnoxious group of people mobbing their way through the store. The next thing I know is that a black guy has shoved his hand in my face to introduce himself,  ugh. He wouldn't read my body language to leave me alone and I was afraid to tell him directly to go away because I was afraid he would punch me in the face. I have experiences with black guys where they try to pick you up and as soon as they realize you are not interested they turn violent. One minute it is hey girl, the next they are in your face and ready to kill.
