When a rapper says "i kill, sell dope, hurt people" there is no other way to interpret those bars
When r kelly says "keep it on the down low, slow wind with me, age aint nothin but a number etc" can be relatable to everyone not fawning over under age children and wouldnt be known to come from an alleged or guilty pedophile without outside source
That is why its easier to separate r kelly from his music
But if rappers WERE actually sellin dope and killing they would undoubtedly be highly respected even if the music was ass
Bruh R. Kelly has lyrics he's written openly saying shit like "Been with you since 16"...he shouted out a 12 year old Aaliyah on a song about sex...or when he says shit like "16 and under" on a song...that's open to different meaning? Writing a song called Age Ain't Nothin But A Number as a grown man for a teenage girl to sing ain't creepy?
