it's hard for me not to perceive as passive violence one's refusal to protect oneself, and imposition on others, who share the same space, of the increased risk maintained through this refusal. it's a bit like farting in the elevator, which is unkind and unpleasant, but with toxic gases that may kill all parties involved. is it really violence to wish someone who fights for their freedom to fart toxic gases, and will do so to make a point, to do so elsewhere rather than in the room whose air you breathe?
