Nobody Not many disagree with that.
Where we disagree is that I consider pro-gun advocates to be making the following mistakes:
1.
overestimating the likelihood of such an event occuring in the first place (specifically, a breakin while the owner is home)
2.
overestimating the likelihood of that owner being both ready and capable of successfully defending themselves during such an event
3.
underestimating the likelihood of an accidental misuse event occurring
4.
underestimating the likelihood of a deliberate misuse event occurring
In my experience, vocal pro-gun advocates tend to hold themselves up as the measuring stick for #2, #3, and #4 when considering "the average person"; I base this on how frequently those same advocates will go into extensive detail about their training, how often they shoot, their knowledge of firearms, etc. yada. yada., tl;dr.
However, I consider the average person to be barely capable of tying their shoes on a good day without written directions*. There is no way in hell that you are going to convince me that the same Quality Individuals™ who made Honey Boo Boo a household name are ever... EVER... going to be individuals who can be trusted to, in a high-risk pressure situation with only a tiny amount of time to make a decision:
a) correctly identify their target
b) ensure that no innocents are downrange of that target
c) operate their weapon properly
This is probably the root of where we disagree. Pro-gun advocates tend to hold up their holy grail of "more training!", and to this I would offer up as a counter all 50 individual state DMVs, and the general skill level of American drivers compared to many other First World countries. We can mandate a certain level of training all we like, and what will happen is that the equivalent of diploma mills will spring up run by "well-meaning citizens", just like "pill mills" and various other certification-acquisition factories for various other industries.
