Well growing up, guns were not really talked about by my parents. Dad had a gun cabinet hung up in the front room but he never really had them out or anything. He had a beautuful Browning BSS 20 gauge and a Ruger 10/22 carbine hanging in it, and I pretty much thought they were just decorations and I never even really asked about the guns. Dad wasn't much of shooter when I was growing up. He had too much on his plate I guess raising two kids and working, because ever since we moved out he has really gotten back into firearms.
Anyway, I never really heard anything one way or the other about guns, for better or worse. I just was taught that they are dangerous (of course) but nothing negative really at all.
I took an interest to shooting when I was in my teens, and me and Dad would go out plinking sometimes. Eventually in my later teen years Dad was fine with me going out to the creek to shoot his 20 gauge or S&W .38 revolver, and of course his 10/22, by myself.
Since then, my love of firearms has only increased to were I am today! So really, I formed my opinions on gun/anti-gun thinking when I was already fairly mature. I like to think on the logical side of the table, and the anti-gunners... well they just DON'T!
So there's my story, I pretty much figured it out by myself and was neither encouraged nor discouraged in pro-gun/anti-gun thinking. I guess I had an innate interest in them, because nobody really taught me how to shoot or took me shooting when I was a small boy.
I'm pretty glad of how things turned out, and glad my parents taught/allowed me to THINK FOR MYSELF, not only about guns but about many things in life.
