I never understood the concept of DADT either. If I work for my money and contribute an amount to the household commensurate with my earnings, what I have left over is mine to do with what I feel like.
In my case, my wife collects Barbies. Currently, her aquisitions are mostly the Holiday Classic Collection models given to her as gifts but sometimes she finds one online she can't live without and she bids. She has around three hundred dolls (she's been collecting since grade school) and ballparking each doll @ $50 means her collection is worth around four times the value of my meager gun collection. More, actually, since some of the guns are hers.
Unfortunately, I'm a fat white male pushing sixty and have been out of work for two and a half years. New guns are few and far between but she will still buy ammo for me so all is not lost. I'm perfectly happy shooting what I do have and if one of my grail guns comes across my path, oh, well, they made more than one of them...
The point here is that, if I can contribute my share to running the house and putting away some $$ in a contingency fund, then what should it matter how I choose to persue my hobby? She doesn't have to enjoy it or even approve, as long as she accepts it.
I mean, after all, do you know how many lap dances I could have bought with the $500 I just spent on my latest Smith and Wesson?
