I was raised in a pro-gun family. They must have been that way for a long time - I recently inherited my great-great-grandfather's Remington Rolling Block #2 rifle (in .32RF). When I was a teenager, we (me, my brother, and our dad) had an unspoken agreement to keep my Crosman 1377 pellet pistol and a supply of pellets by the front door for feral animal control.
Wife's family, though, is liberal and anti-gun. Her father is mostly ambivalent, doesn't see guns as evil, but feels no real compulsion to go out and buy one. Her mom, though, is generally anti-gun. She used to be rabidly anti-gun when my wife and I started dating, so that's an improvement (I think). Chewed my ass out once for bringing a .44 Magnum revolver into her house once, many years ago, but I think she's coming around to the realization that she's known me for eighteen years now and I haven't killed or accidentally shot anybody yet.
My wife's uncle (her mom's brother), though, is a real piece of work. He enlisted in the Army but then decided that guns were bad, so ran off to Canada. He lives in Vancouver, BC now, still not a Canadian citizen, but has now devoted his time to trying to get handguns banned in western Canada (as a start).
The wife was also ambivalent about guns when we were dating, but now she has a stainless Mk.II pistol and a 10/22 rifle, thinks people who use scopes are cheating, and goes about town with a Sig P226 in the car. She still doesn't care much for my ugly black FAL, though...
