Let me be the one to add perspective since I have 20 plus years working within the music industry.
Yes, the BLK community would be different. How do I know this?
Well first, it's a big difference between talking about it vs glorifying it. The difference is '80s and '90s raps talked about it, but not so much glorifying it but giving all sides, via death and jail. They didn't try to make it seem cool and popular as if you need to do what they're doing. They told stories.
Today's rap it's a popularity contest about who has the most hitters in their crew and who can kill the most. It's cool to be a crip or a blood, GD or BD. It's cool to glorify the gang that you're in. It's cool to cause destruction to kill your ops, oh and did I mention that somehow all the "OPs" just so happens to to be BLK?
We need contexts when we're speaking on these facts about rap music. Today, rap music is detrimental to black society because 90% of it, is all about the destruction of self.
Rap in the '90s and '80s was not about the destruction of self, it was a looking-glass into what was going on in various communities. There was also a variety of different raps songs to balance that out. So you can hear KRS-One and NWA along with the ghetto boys and a Tribe Called Quest in your music count down or playlist. Today all Rap count downs are 10 straight songs of self destructive, deplorable acts of violence and self degregation.
How do I also know that our community would be different if rap music with themes of gangsterism wasn't played we would be better off? Because Whity wouldn't spend hundreds of millions of dollars investing in making sure that trap, drill and gangsta music is the only music that's played on the radio 24 hours a day, in all forms of media.That is how you know the difference.
