I see nothing turpitudinous about my stance. I have no moral, legal or ethical obligation to come to anyone's defense. I have absolutely no right to tell other people what to do which also means I respect their personal choices. If a person chooses to go unarmed then he is choosing to either rely on his martial arts skills or the police to come to his aid if his safety or life is ever threatened by a criminal. If that person saw me getting assaulted all they could do is call the cops so why should I do more for them they they are willing to do for themselves or anyone else?
