Of course not.
But to me...the representation of what the black culture is, is from what i've seen from my campus..not trying to generalize, just noticing what i've observed.
Most men, have those long billed baseball caps, usually there pants are hanging below there waste. They curse alot...i hear alot of the times going "Whats good nigga"..they seem to glorify the N word..not sure why..as a jew, it would be like me and my jew friends going "What up Kike?"
But yeah, they act very "thuggish"
I feel black culture is basically influenced by the rap culture..leading to what we see in today's youth.
