I'm not sure what you're trying to prove with it being black on black crime. What's next you gonna argue "well you see slavery was actually in Africa before white people got there so its actually their fault white people enslaved them"?
Look, there is legitimate data out there that shows that violent crime correlates with black people and even factoring in poverty levels, black people still commit disproportionately more than other races. I was hoping the data wouldn't show that but I was wrong and can freely admit that. I know because I did google and research it.
However, I still believe in other factors at play like disproportionate policing of minority neighborhoods, our justice system as it pertains to poor people in general, redlining, the fact that property taxes fund schools, and our general history with people of color among others. At the end of the day, it's really just putting a critical thinking cap on for a second combined with being a bit empathetic to get there. Believe what you want to believe but damn maybe try listening instead of drawing your own conclusions about everything.
