If you don't want to defend yourself, it is your right not to. To say that I cannot defend myself is to say that I don't matter, and those who would violate me do. I respectfully disagree.
The right to violent self-defense is essential to freedom, because if you are forbidden to defend yourself anyone can do their will to you.
Also, statistically, 100% of unarmed people are unable to repel boarders with arms.
