Its true violence is going to happen which is why non violence requires being ready for it to fall on you. If the majority of folks do not follow the system it will fall apart but in falling apart many of those who do not follow it will suffer and die but also those that do.
The problem with violent action is that, to have a chance to succeed, you need a critical mass of support. Not like 50% or anything, but enough that you can’t be easily quelled. The only way you build that support is by suggesting violent resistance to people who scoff at you and accuse you of being unserious until the last straw finally breaks their back and you don’t sound so ridiculous anymore.
Violence is a top-tier solution for lower ranked cognition, where the notion of "hit thing" is a quality solution toward the final stages of attempted problem-solving. Fortunately, people in this situation tend to share the side effect of apathy, so managing to pull together enough "hit thing" people into an organised cohort rarely occurs, or fizzles shortly after take off.
Violence is the supreme authority from which all other authorities are derived.
When all else fails violence is the final answer.
What do you do when someone is violently trying to knock down your door?
You call the police and they come and they ask the person to leave nicely.
He refuses and gets more aggressive, either they restraint him and drag him away or use some other method that involves violence.
I challenge you to show a real world example of ending oppression that was achieved by asking nicely when one side refuses to come to the negotiating table.
“Choose peace rather than confrontation. Except in cases where we cannot get, where we cannot proceed, or we cannot move forward. Then if the only alternative is violence, we will use violence.”
—Nelson Mandela, Gaza (1999)
“Those who make peaceful revolution impossible will make violent revolution inevitable.”
—John F. Kennedy, Address on the First Anniversary of the Alliance for Progress (1962)
