Is antiwar advocacy a Declaration of War?
Yes, according to this online commenter who goes by the name This Was The Moment. He rejects such rejection of violence by arguing “You’ve declared war on war itself” before summing up his poignant contradictions with, “give peace a chance.”

The cognitive dissonance of simultaneously supporting the State and supporting peace perhaps has taken its toll on another hapless victim of compulsory Prussian-schooling.

Whoever thinks peace is war doesn’t understand murdering somebody is not peace. I would say whoever thinks peace is war is sadistic.

Whos rejecting all violence? Not many libertarians are outright pacificts, and mind you there have been just wars.

I regard just action against an aggressor as defense, not violence. I should add that the quote deals with state wars.
