Pretty much what you said Spats, I agree people need to be educated on firearms, but I believe it still needs to remain an option. When we start letting the government regulate what we may or may not need to be educated on, liberty and freedom is lost IMO.
As I stated, there is a very real chance that such a thing would be abused, effectively making it near or impossible for the law abiding to obtain their firearm. Who sets the standard of what enough training would entail to be qualified with a given firearm? There are just so many variables that can go wrong IMO.
I don't see there being a reasonable way to ensure law abiding firearms owners are learning what I think is a necessity, that being firearms safety, without stepping on some or many toes, especially those who wrote the USBoR.
