I doubt she will do any of that, being dead and all.
That isn't what BLM is about. That isn't what they are saying. They literally only show up and protest when a police officer kills a black person in a way that seems like an abuse of power.
Yes, they've been wrong on occasion. Yes there are extremists. BLM is a freaking hashtag. Anyone can use it.
For a moment ignore whether you think their cause is just and admit that the people who support BLM believe it is just. People act on what they believe. People stormed the capitol because they believed an election was being stolen (I think they are wrong), BLM things that a minority is being denied justice. Ignoring them and demonizing them is only going to drive more people to extremes. So at least for a moment, ignore the people who are against BLM tagging the extremists, and ignore the extremists for a minute and listen to the voices of the vast majority. Because the reason we are here is because of them. Most things that can be done to address potential racial disparity in justice are for the good. Body cams, more transparency, better training of law enforcement...all of these things should make policing better whether the complaint is real or not.
90% - The black on black crime thing is an attempt to dismiss and say that "you don't value your own lives, why should we", but almost all homicides are within race. In 2018, the FBI reported that 81% of white victims were killed by white offenders, and 89% of Black victims were killed by Black offenders. That number is fairly consistent year to year.
