People who say all lives matter think that blm is saying "only black lives matter" but what blm means is "black lives matter too" just as much as white lives.   

It's not just police violence either, it's community funding/support, it's actuarial tables, it's redlining, it's minimization of intergenerational trauma etc etc.

I once heard someone say "If there is any statistical difference between white and black people in any category, there's a reason for it." That really stuck with me, because it applies to so many things.
