To be honest, I only know less than a handful of other Democrats, whom I met online, and none of them condone the violence committed by other people on the left. As a matter of fact, they all speak against it. While I can't honestly say that there aren't any Democrats who don't condone violence,
Of course there are some on the left. Personally I remember the wave of rage-filled destruction of cities after the assassination of Martin Luther King and took away that anger was no justification for destruction.
Are you for real?! America was a warzone for a few months in 2020. I was there and saw it myself.
The claim was that BLM was responsible for the violence not that there was no violence.
