Their bluster will backfire. Sooner or later, they'll threaten the wrong person and try to intimidate through fear someone (like myself) who reacts very negatively to folks trying to intimidate them.
Seems like many black women think they can intimidate white folks but back down if confronted. Lived in the city long enough to identify the screamers who lack fortitude. I was sitting at a bank behind two ATM machines that were both in use and waiting to see which car would pull away first. A young black woman pulled in behind me and started screaming hurry up and pick one. I rolled down my window and screamed back even louder, “SHUT THE *expletive* UP! I’LL PICK ONE WHEN I’M DAMN READY.” I was so pissed that day I was ready to get out of the car if need be. She looked very surprised and decided to give it a rest.
