God gave us the gift of life. It is the most precious gift ever. To be unarmed is to be helpless to protect that gift; that is outright irresponsible.
I believe that unarmed truth and unconditional love will have the final word in reality. This is why right, temporarily defeated, is stronger than evil triumphant.
Technically, I am unarmed. But no one should ever underestimate the harm that fingernails can do. Especially if the target is unprepared.
