Is Hawke Newsome advocating violent insurrection?
He's a BLM leader who's been denied a demand he just made.
So, of course he is. It's how BLM believes in responding to any turn of events that they don't like.
and, yeah, bottomofthehill was almost certainly being sarcastic. Dr. King was a known pacifist and devout advocate of nonviolent resistance who encouraged his followers to be the same way, which was a big part of the reason why the Black Panthers/ Nation of Islam crowd (aka the sorts of people whose views were in almost perfect harmony with those that BLM spouts today) called Dr. King and his followers "Chumps" and "Uncle Toms."
