First of all, you cant exactly judge them since many of them make music about their struggles living in the hood. I think music should be embraced regardless of social background, ethnicity etc. the only issue I have with some of the rap music is that many of it can come off as sexist and homophobic. But the thing is that rap music evolves, so you arent exactly going to hear the same style like you did 20 years ago.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
