I don't think you know what art is or what an artist does. So Mads Mikkelsen couldn't expect to be treated like a decent person because he played Hannibal Lector so damn great? That quote is also bullshit as keepsake already pointed out, as there's a lot of conscience hip hop out there. Its just not that much in demand.
Please, enlighten me then, what exactly is art and what exactly does an artist do? Hannibal Lector was portrayed by an actor playing a roll, most musicians just act like themselves. There's no legitimate comparison there.
Because people generally act like themselves, it's part of human nature. Look at the prevalence of violent or criminal behavior espoused in rap and hip hop compared to other genres, and then consider why rap and hip hop musicians are more likely to get into legal trouble for doing those things than other genres.
No, seriously, many, if not most of them play a part, just like an actor. What about Death Metal musicians? You really think most of them sacrifice children to the goat god? I just don't like the generalisation here.
Has a Death Metal musician ever been found to have sacrificed a child to a goat god? Probably not. Compare that to this list of rappers who have served jail time for everything from drug charges to murder. http://www.ranker.com/list/rappers-in-prison-complete-list-of-rappers-in-jail/whatevayoulike Further, look at gang involvement. Why does it appear that rap and hip hop artists are the only musicians that join gangs?
First, if the list is as complete as it says, that's probably not really the majority. Also you use a wrong logic here. Are most musicians who are also gang bangers hip hop artist? Most probably. Does that make most hip hop artists gang bangers? Most probably not.
Also the list shows a lot of crimes committed BEFORE these people became musicians. People can change their ways.
