1. I like guns, but I'm not a "gun nut".
2. My grandfather came here from Poland in 1895 to get away from restrictive Russian laws. He bought me my 1st .22 when I was 7.
3. People who grow up with guns all their lives usually treat them with respect because they KNOW what the gun is capable of. The only people I know who are "gun nuts" are jerks who use the firearm as a penis substitute, much as a old man buying a red Ferrari.
4. I currently own over 30 guns (most of which were passed down to me by my grandfathers and father) and they are all in excellent condition and SAFELY in a locked gun safe (looks a lot like a bank vault and built like one too).
5. My oldest grandchild is turning 7 this year and I'm buying him a single shot .22 (his mother, my wonderful daughter-in-law approves) and he, his father and I will go to the range (daughter-in-law also) and punch some holes in paper. Why? Because it's a lot of fun.
6. On the other hand, you have 4 fingers and an opposable thumb.
