Some subscribe to a soft pacifism where non-destructive violent resistance like disarming the defector or disabling the defector using less-lethal technologies like a tazer would be fine. Pure pacifists who don’t believe in any kind of physical resistance whatsoever are almost exclusively religious practitioners who don’t ascribe a high degree of value to life in this world because they believe non-resistance will bear spiritual fruit in the next world.
I happen to hold this philosophy under different words.
MLK chose nonviolent shows of force, whereas Malcolm X chose more direct forms of violence.
Governments could save face by negotiating with MLK, as he used nonviolent means. They couldn't negotiate with Malcolm X because thats the whole "we cannot negotiate with criminals and terrorists".
MLK wanted a non-violent showing of force as to stay "legal", but a strong implicit threat of "well, you know, theres a LOT of us. We're peaceful for now". The bus boycotts almost bankrupted down in Atlanta, so money attacks also work.
But now, we have No Kings and 50501. The whole idea of mass protest as a 'nonviolent but imminent threat' is completely gone. Protests were a prelude to something to be done. Now, its more of a political action rally, with not much of anything to follow up the initial energy.
Which is also why the protests; pussy hat rebellion, 50501, No Kings - they've all failed. Theres no goals. Its just chanting and some signs.
The important part is that the violence mostly doesn't start until someone tries to hurt those who are there peacefully. Good was there peacefully so retaliation is becoming a possibility.
It's absolutely not realistic. Every right we have was fought for and people died trying to get it. This is especially true in America where a fifth of the population was enslaved at inception. Nothing has never been given to us it had to be taken from abusers of power and there have always been abusers of power in this country.
I mean Trump is no different than Washington. Washington routinely ignored laws, he tried to have his lackeys go get his "property" from free states while never willing to go to court (a provision of the fugitive slave act).
John Adam's called Shays's Resistance terrorists because they had the audacity to close down courts to stop foreclosures of farms (fun fact, that was the first time since the revolution where Americans fired artillery at other Americans (and it was a paid mercenary army by Boston merchants killing over credit)).
You can go down the list, it's always been there but luckily there were always people fighting against it trying to better society against those that simply dragged us down.
