Most people who dont like rap dont like it for racial reasons, or because someone told them not to like it.
I'm sure as a rebuttal someone would post some tired reasoning like "Theres no variety in rap lyrics" or "Rap teaches people to kill" or shit like that.
TOTAL BULLSHIT.
If you want to find rap with lyrical content and messages, its out there. If you want some rap to shake your ass to, its out there.
I've also heard things like "Rap isnt made with real instruments". A big "nigga please" to that as well.
Most of the time, it boils down to a racial issue, as many consider rap to be a "Black" form of music.
