I grew up with guns and with friends who owned and used them in a rural area. I have also been around trained professionals who were new to guns before being trained. I guess some would disagree with me, but I would personally much rather have my old childhood buddies with me in a life and death situation.
I do agree with you that people who have no training or experience should at least get some minimal schooling when they purchase a gun. At least half of that training should be devoted to firearms safety.
