"Silence is Violence."
It seems that the classic mode of anti-war protest (i.e.: gathering en masse with signs and chants) has almost never accomplished anything of significance.
The warfare continues and the puppets remain in power.
The only effective option seems to be a grass-roots effort to raise national awareness of alternative political candidates and parties that can replace the corporate controlled puppets in state and federal governments. The public are continually brainwashed into electing controlled candidates selcted for them by the media.
Simply showing up en masse for one day to express ones self politically will not create change.
