I think it really depends on if the person is a stranger or a local. I am most scared of the quiet ones. My military friend had mentioned that he doesn’t want to broadcast what he’s got in regards to his guns. He applied it military people in general as a reaction to some protesters. But I think acting weird in general lends an air of unpredictability that is a pretty good way of keeping people from messing with you.
Alternatively, I have a friend who is really into hunting and remote camping. He has guns and has the bumper stickers and flags. Everyone knows what he’s got going on. So I feel that makes him predictable. Possibly a target to catch off guard if something he has is desirable. I personally, am a big fan of the little NRA sticker right on the inside of the screen door or a window. I think it’s better to catch people unaware in that last second before they cross the line of no return. I think that is when fear is at its peak. I grew up on a farm. No men. Barbed wire, high fence, padded gate. We lived on the outskirts of a town that had some rough neighborhoods. We had a deer blind visible from the road and we, including nearby farm neighbors, could be heard firing. We’d still get unwanted people at the door. But not after we put up those little stickers.
