IMO, and this is only my opinion, the ones who are the internet douchbags trying to get caught and harassed so they can film it, as well as people carrying long guns into business', is just plain ignorant and it does hurt our cause. It makes me cringe when I see those videos.
What I and most folks I know do, is simply put on our gun as we would, with a good retention holster, tuck our shirts in, dress nice and go about our business. That way people see a normal acting person interacting with others in a social environment and see that nothing bad happened. The more people see that, the more they will go, "Well I saw 2 people today with guns on and they were just shopping." It won't even be an issue with most folks anyway, as they are looking for their brand of shampoo or zit cream . They could care less about me, you or anyone that is in between the door and the zit cream .
The myth about OC'ers being "targets" is ridiculous at the least. Most criminals don't want any resistance, so they pick soft targets . First of all, I doubt they are going to be "looking" for a normal guy to be carrying. They are going to be nervous and not concentrating on any one person, but the group of people they are bothering . If it's one on one, I don't think they are going to pick on the guy with the gun . They want the little gal with the purse instead. If that person is cold enough to shoot you for having a gun, he was probably going to shoot you anyway .
Just my .02 on the subject.
