@vikorr,
The key word here is extreme.
I agree with the basic premise. There is systemic racism that causes police to treat African Americans differently than they treat white people. There is a need for a national discussion about this in a serious way.
The extremism is the problem. The idea that every police shooting is racist doesn't make sense. The claims that police departments are inherently racist is ridiculous and harmful.
The fact is that strong police departments prevent crime. The fact is that most homicides in minority communities don't happen at the hands of police. The fact is that sometimes police need to use deadly force.
You can say "black lives matter"... You can support police reform and ask for accountability. You can also support due process for police officers and give police officers who are doing their job the support that they need.
The demonization of all police and the tacit acceptance of violence and the conspiracy theories we see on this thread are all examples of extremism. This isn't helpful for us as a society in resolving these difficult problems.
I think you and I maybe in agreement at least on some of this.
