If a person wants to harm you, then you have the right to defend yourself regardless of his beleives
Let's look at that statement for what it is.
Self-preservation is the instinctive will to survive. In other words, you WILL defend your life if it is in danger. Only someone who wanted to die or was devoid of mental faculties would allow another to kill or harm him/her. That has been part of us long before religion was ever invented.
So, why would you need a book to tell you to defend yourself if your life was in danger?
