I disagree, having a gun with no training... Is like...
Buying a plane does not make you a pilot.
Buying a boat does not make you a sailor.
Buying some knives and a saw does not make you a Butcher.
IF you want to be able to truely protect yourself, you must get some training.
The problem is, most schools are not geared for the average individual. If you do not have a 1911, or some sort of semiauto you will not do well.
Many times I have trained people["civilian citizens"] with 5 shot S&W's, or small semiautos, for their real world survival. Much different from law Enforcement/Military "stuff".
I didn't say you would be extremely proficient, but I am saying you are ARMED.
If you possess a weapon and the will to use it you are armed. Heck, if you possess the will to defend youself and you don't have a weapon but you are willing to turn anything around you to your advantage you are the weapon.
I have taken many classes both NRA and other, I even was a NRA certified instructor for a few years. I found many instructors take Jeff Cooper's statement to justify their brand of instruction.
I know a LOT of good shooters who are self-taught, some who learned through competition, scouts or hunting. I also know a lot of good shooters whose only training is military service.
I know a couple of old grandmas who are armed. Training is nothing more than going to the range a few times. I don't doubt at least one of these ladies will use the gun if need be.
No owning a boat does not make me a sailor, but if I am willing to learn I can sail that boat, and I don't need anything more than my state class to know the rules.
I don't need a Shaman to tell me I am worthy.
