Why do african americans tend to have louder vocals than the normal person?

you know i don't care if i get a violation or banned i ain't letting you get away with this pal. you are a ignat knucklehead a moron. bigoted small minded dolt. none of what you said is true no tendon no vocal chord. you are ranting against black americans. whites are rude too and if you don't like blacks go back to your cave and stay there
