If you are a pacifist you are negative and self hating. If you allow someone to kill you, you hate yourself. If you truly love yourself you will defend your life. If you are a pacifist you will allow someone to kill you, or you will kill yourselves in self hate. Pacifism loves to say, "I love you." It's at their core of rotten negativity and self hate to desire love more than defending their abilities to love themselves.
Everyone must fight and defend themselves from those who hate themselves and want to kill you because you truly love yourself.
That is all.
