I am anti protests of the type that BLM represents, even if they are not violent.
Creds: I moved into a low-income area and have spent the past ten years providing education, money, and support, trying to improve the lives, and championing the cause of those living in such areas. I adopted a kid with a police record longer than your arm, and worked with him getting detoxed. I spend most of my waking hours on this, all volunteer.
I grew up in the projects. There was a dude some ten years older than myself - a programmer (back before computers were a thing) - who convinced me that I can do something with my life, but I have to take the onus of responsibility upon myself - even when it is someone else's fault.
That's the message I now try to give over - you guys are awesome, and some day you can change this whole here community around. But you gotta take the whole responsibility upon yourselves - especially when it is not your fault.
That's a big message, and hard for me to write in a post like this, but it works. I have hundreds of students that have healthy lives, and we have grown to 30 volunteers who help me.
When there are riots like these it passes a huge message - it is all "their" fault, and "we" deserve everything because of it, and we don't need to take any responsibility.
So, protests have a place. But the way that BLM projects it is, IMO, destructive, even if there are no riots.
Edit: I am not dismissing the bad and uncaring attitude projected by the police or government. I am not dismissing the emotion, anger and sometimes guilt of the protestors. There are protests and other actions that can be extremely useful. Perhaps thought can be put into what objectives can be gained, and how to get them, and then think if supporting BLM is really the way to get them. (Also, I know a few people who have joined BLM protests as a way of protesting Trump. IMO, not the best way to do that, either.)
