Nonviolence is a workable tactic if ones opponent is civilized. SEIU and the Teamsters Union Management are goons with a long history of violence against unarmed opponents. Using nonviolence also requires a free press that will show what’s actually going on. We don’t have that.
Opponent need not be civilized but the culture must be. A deeper investigation of nv power demonstrates it is most effective when it is proactive and confrontational. The Tieneman Square massacre did not produce immediate change but its long term effects have been substantial. The CPC is still the most opressive regime on earth but is acts with greater circumspection. The sacrifice of freedom loving Chinese has not been forgotten. Their bravery will bring down the reign of terror that is the CPC.
