First and foremost, thank you for sharing. I have to say that because most of my reaction is likely to be mistaken as making fun of you, which it isn't.
These isolated tales crack me up. Every time I listen to them, it shows me exactly why we all need to be open carrying as much as possible. It reminds me of when I first started open carrying. That sinking feeling like I was the bad guy. That adrenaline rush as if I needed to hurry to avoid being caught. The exhiliration afterwards as if I had just gotten away with something. That is an emotional rollercoaster with a backdrop of nervousness at the very least that we might be "caught" or otherwise hassled. CRIMINALS don't go through as much. It's truly sad to behold.
What personally saddens me beyond that is the disclaimers the concealed-over-open guys always feel they need to toss in. It's attrocious that they would wish to intimidate or control their countrymen. It's a shame that they've been so dominated by the other side that they're willing to perpetuate their myths in part. If a person wishes to conduct themselves "as to set a good example," that's THEIR choice. If they wish to be a vehement defender of their rights in a way that might not be what the timid consider setting a good example, that's THEIR choice.
EVERY group is going to have a few at one end of the spectrum, a few at the other, and a whole lot towards the middle. If it's really that important to you to make a good impression, then get out there and make it.
