why do white people listen to are music and try to be like

I don't understand why whitepeople listen to are music if someof them don't like us are,i feel they should listen to their music and leave are alone beacuse i feel that music is made just for us not them to listen to, i not against them but i don't understand them i see them wearing are clothes like Roca Wear , Sean John or a shirt with Tupac or a Big smalls shirt.I hope people don't get upset but that the way i feel.
