I've lived in two different states where OC is lawful (NC and VA) and I've exercised it in both. I OC'd exclusively in NC, and now that I'm in VA I will CC about half the time, and OC when I don't feel like trying to hide it. When I OC, it's a 4" XD 45 worn at 3:00. I have yet to have a single problem (knock on wood). I don't consider myself confrontational, nor am I trying to shove anything down anyone's throats.
Also, I don't see how me having a gun on my hip is more of a statement than someone's "Save the whales" bumper sticker, or their "Obama 08" sign in their front yard. I don't care about their views, and most people don't care about mine. The greater majority of people don't even notice it. Most of the time, I get "Is that a glock?". I can count the number of times on one hand that I've been asked if I was a cop, or "why do you need that thing". I just calmly explain that it's my right as an American and that it's perfectly legal. This usually goes into a brief conversation where people ask me about my experience with it, and that's about it. As a matter of fact, I ran into someone in NC a few weeks later, and they had a Sig on their hip.
If it's not for you, then so be it. Just like I don't care if your car is plastered in "Go Green" and "Vote Democrat" stickers, you shouldn't care if I don't feel like trying to hide a gun under my tee-shirt today.
Every time that this topic comes up, it's the same arguement. For those that don't want to OC, then don't. Just like CC, OC has it's advantages and disadvantages. All I have to say is, don't knock it until you try it. If you've have no experience OCing, then (for the most part) you have nothing of value to add to a conversation about OC (besides what you've read on the internet). I don't mean to be rude, really, but if you don't know what you're talking about, stay out of it.
