I never really feel sure how to respond to BLM material.
On one hand, yes of course they do matter, so it's not like I disagree.
But on the other hand, I believe that a heavy emphasis on the racial aspect is counter-productive to making progress.
1. If you look at ALL of the cases of abuse of authority/power by LEOs, it will build a much, much more significant and startling picture than if you focus only on victims of a particular group (race, age, gender, etc).
2. If you build a cause/movement that is against brutality and corruption in general, then every group (race, age, gender, etc) will feel validated in whatever trespasses they have experienced/observed and be far more likely to get involved in the movement. In essence everyone can approach it in a sense of "together we the people are standing up for ourselves" as opposed to "we are going to stand up for on particular group while ignoring the rest of the corruption incidences taking place".
For example, I have a severe mental illness that is managed with psychiatric medication. There are many cases of mentally ill people being brutalized and killed by police. There are many instances of police not having proper knowledge and training in approaching and handling the mentally ill, which likely contributes a lot to the tragedies. Also, a very large number of mentally ill people are in prison, as many facilities in the past (corrupt and inhumane asylum type places) were simply eliminated as opposed to being ethically cleaned up.
So if there was a movement against abuse by law enforcement in general, people like myself would be one of several voices within it. I would much rather that than having a "Mentally Ill Lives Matter" movement, because I would rather a movement be uniting and powerful.
