Terry is getting shit because he is making the typical rightwing "black on black" crime argument. That argument is fallacious and it has a lot of problems in and of itself, but regardless, it isn't what BLM is about.
BLM started, and is SPECIFICALLY about the criminal justice systems discrimination against blacks. That's it. It is not LITERALLY about the preservation of every black life, but that also doesn't mean that it is against or ignoring other problems in the inner cities.
Terry is playing a really dumb game of semantics and word play. So BLM should have called their movement "Don't Shoot Black people please, police" instead?
If Terry wants to create a movement to address the specific issues going on in black neighborhoods, awesome, he should do that. But that isn't the main objective of BLM, so it makes no sense to criticize them for not addressing an issue that they never were trying to champion.
I like Terry. I think he is a good dude with his heart in the right place. But he too often goes to twitter to send out his thoughts without doing much reflection and thinking first.
This isn't about having "the right black opinion", his argument, and the argument of "black on black crime" is not what BLM is about.
And making it this all encompassing ALL LIVES MATTER or LITERALLY ALL BLACK LIVES MATTER movement would just make it a useless slogan that wouldn't bring about any real changes. The issues of poverty and crime in urban areas are a lot more complicated.
