It's amazing how his protest makes some more angry than what it is he is protesting (public executions of black and brown people at the hands of police).
Most of them aren't executions. Oh sure, Walter Scott was. But Michael Brown wasn't. Alton Sterling wasn't. Trayvon Martin wasn't. Slyville Smith wasn't. These were lawful cases of either self defense or armed felons resisting arrest.
And who are you kidding. Brown people? Liar. You don't care about Latinos killed by police. That's not part of the big lie.
Answer the question. Who was responsible for slavery?
Which slavery? The trans-Atlantic slave trade? The Barbary Slave Trade of Europeans across North Africa? Modern day slavery in the middle east or North Korea?
I assume you mean the trans-Atlantic slave trade, since that is the beginning and end of history in your black supremacist world. Well, certainly the American colonists bore some responsibility. So did the Zulus of Africa who tossed their own people to the lion's den.
Well, other than "that <thug / criminal / hoodlum> deserved it!"
Correct. When you study the facts of the case, there was no wrong doing in the
execution justified shooting of Mike Brown. And this thug criminal hoodlum in Milwaukee? The one fleeing a traffic stop and trying to shoot a
coon black cop? Good riddance.
