Personal safety and personal statement. It is my right to carry- especially since according to my state's law, as an able-bodied citizen over the age of 17, I am a member of the State Militia. I believe a right unexercised is a right lost, and that's something I am 100% unwilling to lose.
Plus, I determined long ago that my days of being a passive victim were over, and I was never going to let myself be caught in a position of weakness again. I know better than to carry in Condition White.
I don't care about your personal statement. You would NOT be allowed in my home or on my property with a gun and if you brought the gun in above my objections because you had to make your "statement" you'd loose a friend. In fact you'd loose all the friends we held in common.
Concealed or not concealed, guns are not welcome in most of our homes. And those that would allow the gun would be taken a back by you disregarding the wishes of the home owners.
People have a right to feel safe in their own home, They have a right to set up rules to make that feeling a reality, a guest does not have the right to over ride the wishes of their hosts. Since you've said that if a person has an issue with it, I'll answer your other question. yes it would be rude ( very rude, in fact) to walk into a home with a gun with out know how the home owner feels about it. Ask first, if you don't know them well enough to know that they'd welcome the gun, they don't know you well enough to know why you are carrying it.
If someone says 'By the way, can you leave your gun outside', then I have absolutely no problem with it, and will respect the wishes of the home owner, of course. If someone approached me randomly in a public place and demanded I remove my gun, I would be less polite.
I believe your home, your rules. In the public sphere, I follow the law, which says open carry is my right. If asked to remove my gun from an establishment by the management, I would remove myself as well.
My question was not to get into my personal reasons for carrying a gun. It was how to bring up the subject, how to find out whether it was welcome or not... and maybe how to avoid a horrified diatribe of just why I should not carry when I mention that I do. Again, I don't want to insinuate to my acquaintances that I believe they have never noticed my gun (to me, that would be the same as going 'By the way, I don't know if you noticed, but I'm a woman.') and I don't really want to get too deep into my reasons with people I don't know very well ('So, I've been the victim of sexual intimidation and have a correlating deep-seated fear of being violently raped that flares up to enormous proportions every time I'm in a city. Plus, I based my decision of a careful reading of the United States Constitution, the Bill of Rights, and a long study of the writings of Thomas Jefferson.').
Thinking about it, if OCing into a gun-friendly home, I'd probably do what my boyfriend does. He comes in, asks where it would be safe to put his gun, and puts it there for the duration of his visit. I tried sitting down with my gun strapped on today, and it's really uncomfortable (I haven't open carried yet, since I just got my holster yesterday).
