If this is gonna work (I don't know for sure it will) at least it is important to be "clean", as in no talk of violence/revolution and so on. Ghandi is a good role model I suppose.
Violence breeds Violents. We must convince violents that they have more productive things to do than waste time and resources chasing shadows.
To me, this is a complicated issue. There is danger of becoming what you fight if you use "their" tools. And I get the feeling your analysis while seemingly logical is too simplistic
A people get the government they deserve. I believe this has much to do with attitude and what they allow, and that if the people are properly against something, it cannot take root.
Some interesting trends in that regard: Australia is obviously getting what people (I know there) want: Utter Totalitarianism. Others seem ro be quietly slipping away from such.
And I am not so sure that violence is needed as long as the disease of accepting bad things is avoided. Or maybe some "violence as last resort" is needed, hard to know for sure.
Self-defense is a last resort should only be reverted to when there really is no other choice. It is far more profitable to pre-emptively outwit violents than to play their games.
I have zero issue with convincing sociopath tyrants and psyhopath tyrants to consume themselves with violence against each other while the rest of us observe from a safe disance
