If voting is participatory government (common opinion) and if government is a territorial monopoly in violence (common political science definition) then it follows that voting is participation in violence.

I am aware that contrarian voting is a frequently suggested strategy to signal disapproval, but I am not convinced it is effective, and the lower the participation rate overall, the harder it is for those in power to claim a public mandate, especially when the majority of eligible voters did not participate at all.
