This is doing numbers but the real truth is scarier. They don't know what "self defense" is in the white sense of the word. It's a foreign concept. One of hundreds of things about living in a 100IQ average society they are incapable of comprehending.
The Karmelo Anthony ordeal boils down to the simple fact that a non-trivial number of black people believe that they should be governed under a sovereign hood code, and any white person who is in proximity to a black person consents to be governed under hood code. This means that any interpersonal escalation, regardless of the degree of escalation, creates the grounds for the exercise of deadly force to defend one’s “manhood.”
They do not think they should be required to submit to the law of the white man. If Karmelo were being tried in a court applying “hood code” he would be completely innocent because he murdered in defense of his manhood. So it is not that they are just pretending they believe Karmelo is actually innocent, they genuinely do believe he is innocent, but under a different set of “laws.” They therefore understand this to be a “modern day lynching” in the sense that Karmelo is being forced to submit to the law of the white man, and therefore his right to murder on behalf of his manhood, which they do sincerely believe is his right, was “violated.”
