Wiki - The paradox of tolerance states that if a society is tolerant without limit, its ability to be tolerant is eventually ceased or destroyed by the intolerant. Karl Popper described it as the seemingly self-contradictory idea that in order to maintain a tolerant society, the society must retain the right to be intolerant of intolerance.
Please provide an example of "objective harm". You referenced this concept. You have clearly demonstrated that this concept is essential to understanding the model you have described, but I do not understand what you mean by that statement. Please provide an example to aid my comprehension.
Yes, I understand the scenario, but the context of intent changes everything.
Let's agree that it's all "physical violence" as defined as: they are both physically damaging each other and causing harm.
But depending on the context of intent that "physical violence" breaks down into two more nuanced types of physical violence: Defensive Violence and Offensive Violence.
Defensive Violence can be logically justified, Offensive Violence cannot.
Edit: If I had answered your question as to what is an objective harmful act, I could have been more specific and clarified Offensive Violence.
Generally speaking, I would agree on your characterization of violence.
However, I am required to suspend my own feelings and opinions on these scenarios. I realized that I cannot actually answer your last question. I can objectively state that both the Nazi and the Jew were injured, but I am forbidden from saying whether either injury constitutes "harm".
I think I can state that the shooter-Nazi believes his force is defensive, while the injured Jew believes that force was offensive.
I think I can state that the shooter-Jew believes his force is defensive, while the injured Nazi believes that same force was offensive.
