I wanted to address this post specifically.
Blaming outside groups like Antifa (whose mantra is standing up to fascists with force if necessary, not property destruction) and alt-right groups for the destruction and looting is an age-old tactic used by those in power to deny authenticity from the aggrieved and to try to divide and conquer a movement, in this case mainly people of color, younger people, and organized groups like BLM. Certainly some people are opportunistic and certainly some far-right groups like white supremacists are trying to provoke, but by in large the destruction is caused by the protesters.
Don’t Fall for the Myth of the “Outside Agitator” in Racial Justice Protests
We Have Seen the ‘Outside Agitator’ and He Is Us
People are rightfully pissed off. Peaceful protests have been tried for decades now, and we are no closer to true racial justice than we were in the 1960s. People of color still bear the brunt of the law enforcement and of our hyper-capitalist society and things are only getting worse. What do you expect pissed off people to do? Continue to carry signs and march? Vote for one of two parties who serve capital and not the people?
Peaceful protests have been tried. They have failed. Look throughout history: every major victory for liberty and justice has been gained by using violence to some extent. I'm not specifically calling for violence but I'm also not going to condemn anyone who feels like they are pushed to the brink.
