I really don't understand this fascination with shooting each other.
Most of those that I know to own firearms have no such fascination. I don't think the writer of these rules has one either. Anyone who states the following, simply is not looking for a fight of any kind:
23. Your number one option for personal security is a lifelong commitment to avoidance, deterrence, and de-escalation.
However, if one is threatened, the rules may be good information. It's not bad to think about the what ifs, just in case.
In the same vein, I am not looking for a disaster of any nature to befall myself, my family, my friends, my community, my country ot even my planet. However, I know they will occur. I know they will occur to those about whom I care, and maybe to my family and myself. It's not bad to think about these what ifs either, just in case.
