It is not an insult to anyone to assume the killer was black.
As anyone with half a brain and any knowledge of relative numbers of black on black vs white on black murder rates would know.
If the truth is that painful to you, then maybe you should be spending more time addressing that, instead of defending murderers.
Of course its an insult. Its like me assuming you have hair lice since white people catch lice all the time.
According to the FBI, there were 2,245 black on black murders in 2013 compared to 189 white on black, and the second number includes hispanics.
If the ration of whites that had lice was equally lop sided, then no it would not be an insult to assume that a random white guy had lice.
What is that, approximately 22 to 1? And THEN you want to subtract out the Hispanics so probably more like 35 to 1.
ANd you want to assume the killer was white?
