"...You are saying that extreme black on black violence and carnage is not news for the MSM.
Is that correct?..."

No, you're saying that to create something out of nothing.  If one isn't smart enough to dig deeper than the fluff that's thrown in their face by biased news media (which exists on ALL sides), then they're probably an idiot and not worth talking to.  

The problems in Chicago do not preclude the problems in Charlotte, the idiocy of Trump, any extreme left wing group that supports racist behavior, or any reprehensible behavior at all.  Even a person of average intelligence can consider many issues without having to exclude the others.  

The problem we're dealing with here is that those with questionable behavior immediately deflect and try to point at problems elsewhere, and those that support them do the same.  Reality is Trump is a racist who is supported by racist morons and he didn't have the courage to call them out, just as many other politicians have done.
