It was not a metaphor. You said you would never fight unless someone took a swing at you. If you walked down the street and spotted a person beating another helpless person to death, would you stand by and do nothing because you had not been attacked?

Also, drop the condescending tone in your response about 'helping people see another way'. I gave you a simple hypothetical and you dumped a page of text without answering it because you didn't understand a simple question. You're not helping at all.
