As for the first question, I usually come back with the responce that the Bill of Rights doesn't state that we have the right to bear only the arms we NEED for hunting or sport shooting. It states that we have the right to bear ARMS (PERIOD).
As for safety in the home. Well, a firearm is only as safe and the nut behind the trigger. SHOULD all owners of firearms be fully trained before owning a firearm? By all means yes! Only full and compleate training can insure safety. So if that is the case, then why not make training a requirement before allowing people to own firearms? Believe it or not, I used to believe that we should. However, if one could afford the firearm, but not the training, then wouldn't that mean that the government was "Infringing" on that person's "Right to Bear Arms?"
Do you realize that thousands of people every year are injured in accidents in their home workshops while woodworking with powertools or working on their cars? Millions every year are injured in their kitchens working with sharp knives, and hot stoves. Should the Government step in and make it mandatory to recieve safety training before allowing it's citizens to work on their cars or prepair their meals? How stupid would that be?
The bottom line is that we are supposed to be responsible adults. That means that we bear the responsibility of both our own safety and the safety of those around us. If I buy a new tablesaw and don't get trained or even read the manual, and end up slicing off my finger, well DAMNIT I should have known better and it's no ones fault but mine. The same thing goes with firearms. It's my responsibility to get the training I need, and if I don't, and I, or someone else is harmed by it, then it's my fault as the firearm's owner, and the Government has no more business controling my firearms, than it does contorlling my Tablesaw, or kitchen knives, or any other tool you care to mention.
It's high time that we all grow up and start being the responsible adults that we claim to be. It's also high time that we start telling the lawyers and judges who want to hold everyone accountable for the actions of the criminally stupid, to pull their collective heads out of their asses and realize that people have to be held accountable for their own actions!
OK, I've vented and I'm feeling much better now.
