1. Do you feel whites have a right to enjoy the music? Do you feel disdain when you see white people listening to "Black" music?
Yes. I think it's nearly impossible not to have any admiration for people you think they're strangers striving to prove you they know your language as much than you or better than you.
2. How do you feel about them, say like the Kendrick experience, when they rap or sing it back, using the exact lyrics even if they used the N word in the song?
I don't know the hip-hop scene enough to answer. But the lyrics are the lyrics, and the lyrics are sacred. You don't want to sing the N word you don't sing the song at all.
3. How do you feel about white rappers in general?
The same thing as white Blues singers.
4. What do you think appreciation of rap music should do for your community?
Black people are also a community. Some may be friendly, but you don't mess with them.
Someone messes with me means action will be taken. Others think the same. Everyone and each community has to seek his interests.
5. Is there a right or wrong way to handle this topic?
No, unless it's a wrong way to handle someone.
6. If you are comfortable, this is completely optional, what race do you identify with?
White.
I definitely think culture is shareable, but must not be appropriated lightly. There are Black people who don't have any problem to give my wife an African hairstyle, but I'm not going to C-Walk in front of Crips or walk in Harlem shouting the N word.
I mean, an African hairstyle doesn't make my wife African. Pretty much like wearing a military jacket won't make you a military. Wearing civilian camo is fine, but wearing actual military jackets (e.g. with unearned insigna) while being civilian is stolen valor.
I mean, if some culture has been declared clearly a community's property, you don't take it if outside that community, unless you want to get into conflict with them. If some Black people give/sell some of their culture (e.g. music or hairstyle) to White people legitimately, it means they don't have too much problems with that.
Hip-hop is one of those kinds of music that say "we're not a bunch of Care Bears", and military music is more or less the same thing.
