Granted, that was somewhat tongue in cheek. However, this next example is not: Even more dangerous than those who are too volatile to carry a firearm, are those who are too timid to carry a firearm. Some people by their gentle nature, and may God bless them, simply are not prepared to bring deadly force to bear. Still more will hesitate before committing to the ultimate act of violent defense, and lose the opportunity. In both cases, all such a person would gain by carrying a weapon would be to avail the assailant with a better means to do them arm.
Weapons should only be carried by those who are prepared to use them, and that's a decision that each man or woman has to make for himself or herself. It would simply be insanity to take that decision from the individual.
