In a world where Black Americans can't reasonably expect the authorities to not shoot them essentially for being Black in America, they can ask for racist, pro-slavery symbols or guns or similar to be edited out of popular fiction or removed from public spaces in the form of statues and maybe get it.
I recall reading that some Black artist was told his song about wanting to kill the cops was not okay. Cops can kill Blacks. Blacks can't sing about how that makes them feel.
So not all people are equally allowed to express their artistic vision or their feelings or their lived reality and it's too much to ask to be treated like human beings or even allowed a voice of their own, so the ask is for others to tone it down as a hoped for step in the right direction.
I don't know what the solution is. I wish we (in the US) fed people in prison better and had enough decent affordable housing for starters but even those modest goals seem completely out of reach.
