One impression I get from reading this and other threads is that many believe the same thing that the anti-gun crowd believes, which is that guns are much too dangerous for ordinary people. By the same token, there is the common belief that the world in which we live is a very dangerous place. The anti-gun crowd believes fewer guns would be better, and the other side believes the opposite. I think some of the same exaggerations have been made by both sides to further their arguments.
Thats a false impression and a leading argument. I think most people arguing for training are arguing that people should be sufficiently trained to not be a menace.
With rights come responsibilities. If you're going to avail yourself of your 2nd Amendment Rights you should be responsbile and at least know how to handle the blasted thing.
