I don't really know. My father served in WW2 and landed on Normandy in later life he was totally uninterested in guns so he was not a reason.
My grandfather was a great shooter of birds but I never met him.
My best guess was TV, as a kid when Combat was on, I was there.
Had my first handgun when I was 14. Legally, 44 cap and ball which I still have and shoot.
I am addicted to shooting sports and I need NO cure.
