Your statement is fair in that, if unjustified, you're no longer defending. I was not speaking of pro-active defense. I assume you know and wanted to make a separate point?

No I’m not. But if you are interested in those kind auf thoughts, look at Mises.org and people like Rothbard and Hoppe
Okay, but where did you read/interpret the 'pro-active' conponent from?
“If you claim you're only allowed to fight back in kind, sure, maybe that is a valid argument. I am not sure whether that is defensible for all rights. In some cases, your attacker might be at an inherent advantage. That would be a good reason to fight back in whichever way is to your benefit.”
Maybe I did misinterpret, but it sounded to me, that only self defense ist not sufficient for you.
