It serves as a reminder to me of how we take our freedoms and knowledge base for granted. As a Texas resident, I've always "known" I don't have to register my guns, nor do I need a "permit" to buy any more guns, and that I can make a private-party deal with anyone I feel comfortable buying from or selling to.
But as the "go to" guy in certain circles, people ask me ALL THE TIME what they need to do to be able to buy a gun. Even Texas residents that have never lived (or even been) anywhere else are shocked when I tell them that they just go to a gun store, pick out a gun, fill out a 4473, show a DL, pony up the cash, and head home with their new gun.
Too much pop culture telling people that all guns can be traced, all guns are registered, everyone has to have a license or permit, etc. etc. When you point out that none of this is true, they're shocked. I actually think the "assumption" that guns are registered, licensed, and traceable is part of the reason there's so little pushback from outside our culture when new regulations are proposed -- after all, if you already have to register, be licensed to buy, etc., what's the big to-do about another law???
My overall point here is this: We take our "expertise" for granted--most of us have forgotten more about guns, shooting, shooting sports, self defense, and the laws around all of it than the average layman will ever know. Although I never have really considered myself an "expert," its been pointed out to me that I am indeed the expert in most social environments--and this is true of all of us.
