Taboos around violence for political are one of the crucial building blocks for a functioning democracy. If those taboos are broken, even for a good cause, you set a precedence that violence works. And the next cause won’t be as good. One only has to look at the lessons of the Roman Revolution that started with the murder of Grachus, and ended with an Emperor who everyone acclaimed as they were so tired of the bloodshed.
This is incoherent. You can't claim to not condone violence and in the same sentence say but actually it works.
I see in another of your posts you said something to the effect of "If (protests) become violent, don't be surprised when (the police) respond with violence."
This solidly frames the protesters as the sole provocateurs and the police as solidly the ones that are backed into a corner. It's almost as if your argument relies on ignoring the literal murder of George Floyd when looking at the timeline of events.
To paraphrase a joke I saw a while ago, "If a police officer were kneeling on my neck, I would simply vote that officer out of office." It's patent nonsense meant for amusement, but the line of reasoning is similar to what you can construct out of specially selected MLK quotes or whatever.
You must have me confused with someone else. I've never made a comment like that.
