...I'm talking about initiating physical violence or threat of violence, and I'd like to hear someone make an argument defending doing that...
I lived in several US states allowing me to use violence to protect my property. You [nonviolently] come on my property, I shoot you in the face.
What's wrong with that?
That's why I very specifically wrote "INITIATING" physical violence. Self defense and defense of one's property is not initiation. Can you fucking read or do I have to ignore you again?
