Dear Health,
Peaceful demonstrations seem to stay on track toward the original goal in the long run.
Violence could be more effective, when the problem is that nobody is willing to talk for/to you.
The ideology of violence (as far as I can tell) is reserved for when the subjugated, or those who think they are subjugated, understands the oppositions thinking a certain way. And according to that understanding, the opposition would never really give ground, because it undermines their whole sense of self. This is also behind the ideology of war. As well as competitive sports. (The yankees think the red sox would not allow the yankees to win the world series, as that is part of the red sox’ identity.)
