Love how you're into this 'music.' Never heard of them.
How's your Taylor Swidt love life going by the way, Lady MaGa?
Again, not culture, which you still have not looked up. Also, you're trying to pull a "Which came first, the chicken and fried egg?" so still no.
"And kids in the ghettos are affected by this, wanting to be in gangs and thinking drugs are cool."
What are you, 82? "And now the kids want to take the marijuanas because Bill Clinton played saxaphone on that dastardly Arsenio Hall Negro show"
To wrap up this silliness, Country, Blue Grass, and Blues - which evolved over centuries (and are descendended from music far older) - are culture. B-Boy, Death Metal, Grunge, and Emo are not. They are fads.
B-Boy Music, or 'Gangsta Rap' that you refer to, is product, an expression of what some witness, exagerrated and sensationalized for marketing purposes. In fact, you might want ot look into accusations of why such is being mass marketed by large corporations.
In additon, the largest demographic which purchases this 'music' is who? And yet do you see these white suburban kids pimping, shooting up cops, and smoking crack?
