Most gun owners are white, middle aged, males who usually live in rural places. (There's a study on this from Harvard, but I'm too busy to look it up)
Now, with that in mind, in what world doesn't self defense classes help? In what world doesn't a parent escort a 12 yr old girl or at least have good friends to take care of them?
You need a gun to protect yourself? Chances are they are owned by a white, middle-aged, males. You have a home invader? Use a bat. You want to go hunting? Use an actual hunting weapon. (I hear bows are much more fun)
Sweden got away with gun control, so did Britain. Were there anymore rapes, murders, and thefts? Actually murders went down while the percentage of thefts was the same as the US. In fact even rapes dropped slightly from 32% to around 25%.
Though you want more guns? I'm sure Hitler would agree with you. Why not? He did lift the League of Nations gun ban in 1930.
