Every time a #BlackLivesMatter protests leads to casualties, the media claims that it "turned violent". That's a weasel word.
Peaceful protests don't turn violent. #BlackLivesMatter protests transition from violent rhetoric to violent deeds. BLM protests are animated by exterminationist claims about police genocide and a war being waged against black people.
When that's your worldview, your protests might occasionally be non-violent, but they are never peaceful. They become violent when some BLM supporters transition from rhetoric to action.
It's time to stop the false narrative.
