Unfortunately, everything stated here is false.
The argument and the rebuttal are both wrong.

In all of human history there has been us and them.
Us, our group, those near to us, those we rely on and know.
Them, everyone else.

Blazing Saddles did more to end racism than any BLM anything ever did.
And that is the way to end racism. Get people to know more about other groups. When you have something in common, they are no longer a them.

And, the comment "Blacks are being murdered in cold blood..." is the problem.
Whites, arabs and asians are being murdered in cold blood too.
And no one gives a damn about them. Even though there are more deaths of these groups, in number and in #/10,000.

So, as a last word. I understand your rhetoric.
I also understand the actual situation.
And what is being spewed out right now, by both sides, are what they were programmed to say.
You were programmed to say this.

Why hasn't any BLM stood up and said "The FED has been making black communities poorer and poorer, we should End the FED!"?
