It would be nice if you could leave the personal attacks out. They are the last resort of those who know they have a weak argument. You sound angry. Perhaps your quick emotional response is the reason why you have had to use a firearm three times.
You present two very different scenarios. Using a shotgun in a home defense situation is dramatically different from self defense outside the home. I am a proponent of having people arm themselves, but not everyone has the knowledge, skills and attitude required.
Peace.

You come off as very elitist in your thinking. Using a firearm is not rocket science, and being highly skilled is not required to be lethal. Certainly not required to be better off than bringing a 90 pound body to a fist or bat fight.
Attitude is king, not quick draw, or the ability to shoot a 2" group at 50 feet. Calm and deliberate is vital. Of course more training is better, but very little training can make a person a whole lot safer.
FYI, the first time I used a gun I was a teenager and saw a beating coming on when I asked a group of men to get off of our farm. They walked back for their guns.
The second and third was when I flipped houses in a bad part of town and had pairs of people walk in on me expecting an easy mark. As I'd never met any of the individuals I much doubt that my lack of cordiality played any part.
None of the above should be read to say that training isn't good, it is, and more is better.
