I started shooting at 9, clays on a farm. Carried on in the cadets and then the army. Turns out I have a natural talent for it and always came if not top, then top 3. I like shooting, I can live without it too.
I have spent a lot of time shooting and hunting with family in the states and I can tell you they take gun safety very seriously. Even though I am qualified to be in charge of a military shooting range, they still wanted to test my safety skills before letting me out on a hunt with them. I have never come across the types shown in that programme, but to say they dont exist would be a falsity, but from what I have seen they seem to be a small minority.
I guess that programmes like that try to showcase the worst case scenario as the norm and play on our stereotypes of gun-loving americans. If you lived over there and watched benefits street you would think we were all like that Dee woman but as we all know, people like that are (thankfully) a minority. I hope you get the analagy because their views on the NHS are somewhat skewed due to the political agenda against Obamacare, but just like this programme, they took a minority problem and made it out like the entire system was that way.
