First of all dude is clearly upset. Getting shot and almost dying yourself is one thing. But having your child get shot, eventhough she survived is a level of trauma that I wish on no one. I can't imagine how he felt when he heard that shyt and I would never want to know what it felt like.
Two things can be true. Black folks have been and continue to be opppressed, marginalized, and treated like less than humans. This contributes to the ills in the community. That doesn't mean we can't/shouldnt' check ourselves. Feeding into white supremacy and doing exactly what they want us to do doesn't help either. You know what else is a result of white supremacy/systematic oppression? c00nery. Sell outs. These people don't just wake up and say "Hey let me just sell my people out for no reason". No they do it because that's what they have been taught and/or they see that as the best option for themselves and their families. People don't have any problem telling them to check themselves though. People are able to seperate personal responsiblity from injustice when it comes to them. One of the biggest problems we have is that we dont' recognize the black folks out here harming each other or pushing a lifestyle that invlolves doing that as the c00ns/sellouts that they are. When white folks or c00ns say "Bu...bu...but what about black on black crime" in response to another state sanctioned lynching we know what that is. That is deflection. It is an attempt to shirk responsbility and rationalize evil shyt. However, when a black person that by all accounts genuinely cares about his community says we gotta check our shyt, in response to some shyt that happened in our community, that is what they are supposed to do and we should listen.
