There are plenty of ways and you use them everyday(1). But my point is that it does not matter. If you cannot figure out how to protect yourself and you suggest me to follow your gun (or some representitive's of yours), then it's just silly.
(1) you put locks on your car, apartment and bike. You have passwords. You don't tell people left and right where you live and how much money do you have. You have insurance. You hire guards, set up cameras, build up reputation with people you work with. You document your agreements to show to others in case of a conflict. You choose safer districts and don't go where it's unsafe. You choose to live with other people seeking peace and protection, rather than with crazy lunatics. You minimize risk voluntarily: individually or together with others. Without any "moral theories" or justification for any violence.
