I assume this is another article trying to be controversial and edgy by pointing out that BLM are against police brutality but not angered by the rampant black-on-black gang crime.
What the idiots that make this argument are failing to recognise is that there is significant evidence to suggest that, overwhelmingly in the US, black people are targeted by the police because of their race. Black-on-black gang crime does not involve black people being killed because of their race. One scenario is racist, the other is not. That's the difference. It's pretty simple and anyone with a braincell is sick of the ridiculous comparison.
