Tam builds an ontology for people that own firearms; examining it, I’d have to say I’m in the “none of the above” class. I can rule Trainer, Collector, Hunter, and Gamer out right off; this leaves Owner and Shooter.
Although I’m active in fora, I shoot once a year or so; I spend lots of time on the hobby and would list shooting as a one, but the range time attribute is very far from my level of participation in the sports surrounding firearms.
So why not Owner? Owners don’t do NFA. Owners don’t do political organizing. Owners don’t buy 1200 feet of paracord to cause other owners to spends thousands of dollars on ammo they otherwise would not have spent. While I am certainly an owner, I am not an Owner.
A suggested class is the Spender; I’m not that guy, either. I won’t argue EOTech versus Aimpoint nor 5.56 versus 6.8 versus 6.5. My gun stuff gets used (slowly) and abused (broke my 50 BMG rifle 3 different ways this weekend); I don’t (yet) own a single-point sling.
As such, I think I’ll be content being an owner. Perhaps a more complete ontology will include “NFA owner that shoots once a year, is politically active, and loves to see you burn barrels in frustration”; you know what they say about ontologies, though.
