I guess the difference is I educated myself on the laws by looking them up myself instead of going by what everyone else says. It provided me the confidence to OC without concern for the legality of it. It also provided me the confidence to stand up to a LEO who tried to criminalize my OC once.
As for what other people think, I really don't care. I lost respect for the opinion of the public at large a long time ago, you know, back in school. The way I looked at it from the start was if they are scared, let them be, it's not my problem. If they can't reason it out by realizing that a criminal doesn't stand patiently in line with his sidearm in full view, then I guess they'll figure it out once I walk out the door and no one got shot.
Some say, "Oh we should be concerned, because if enough of them are scared then it'll ruin it for the rest of us." Let me be the first to say that's bull, 90% of the people out there are too concerned about the next episode of their favorite TV show or what they're doing that weekend to care about phoning legislators or trying to start bills to outlaw something that has been a part of my particular state's constitution and heritage far longer than anyone who's reading this has been alive. Good luck with that.
My point of the original post was that it is your right and if you act scared to exercise it, if you allow public opinion to deter you, then you leave it open to be taken away. If you are timid about OCing, then you will probably be timid about using it when the time comes and that will cost you your life.
