Fact of the matter is that no matter what you believe, a lot of violence happens around BLM rallies and no matter what you believe, that violence does not help relations in any way shape or form.
The best thing to do in anyone's position is to try and distance what group you associate with from any sort of violent actions, otherwise you're going to be associated with the violence, because at the end of the day your movement means absolutely nothing to anyone if they think it's involved with spree violence and looting.
