I would find such a rule ridiculous. But then, I make it a point not to hang out with, befriend, or shoot with people to whom I wouldn't trust giving a firearm.
I agree with this statement completely. I have probably ten guys that I will let handle my guns, and my most common shooting buddies don't even have to ask. On occasion, I have shot with groups of new shooters, and I have guns that I will let them use, and guns that I won't, but that isn't based on value or persnicketyness as much as common sense. I have a couple "spare" .22 pistols and rifles, and it is much cheaper for a new shooter to bang away with those than it is my AR, or one of my .45s. If general safety rules are followed, they can handle my stuff all they want. If something happens to break, well, 99% of the time it's cheap and easy to fix. I will say that I am a cold-hearted bastard is someone is unsafe with my stuff or around me. It's a privilege to handle my stuff, not a right. My two main shooting buddies are the only ones that basically have unrestricted access to what I bring to the range, because I know neither one is going to goof around.
That being said, your clearly a different guy than me, and you have different expectations. I carry concealed, and I have said repeatedly I could care less who knows it. Right there, that shows clear differences in points of view. I will talk about guns anytime, anyplace with anybody. If someones want to know what I have, I will enthusiastically talk in general terms about my military rifle collection or my pistols or whatever they seem to be interested in. But, thats just me. Some guys like to be quieter about it, some guys like to yak about it. In the end, it's your property and you can restrict access to it as you see fit. I don't let but one other person touch my guitar for pretty much the same reasons you don't want someone touching your guns (minus the chance of accidental death, lol), so I can dig it.
