This is MOB rule, no different than the Vietnam war protests, civil unrest, and riots. The mobs were wrong then; they are wrong now. Social change via mob rule does not work on a lasting basis because it has no foundation. Martin Luther King got it right, but nothing since.
Please post the quote from MLK.. was this MLK, Jr? The left took seeds from his peaceful pursuits and twisted them into terrible things. He was really quite brilliant.
