I can sympathize with the OP not so much on the open carry bit so much but rather there are those who would ruin it for the rest of us. My first CCW-capable gun was a Ruger Security Six .357 Magnum a few years back when I was 21 and had gotten my CCW permit a week after I bought the hand gun. Turned 21 and got my grandfather's old 7.5" SBH .44 Magnum, day after I turned 21 I bought the Security Six, and a week after that I took the class and waited my sixty days, sent out the paperwork the same day I took the class, got my fingerprints done a few days before I took the class.
Now my friend at the time (no longer friends because of his continuos poor choices), he was an idiot. Bought a Taurus PT145 and showed it off constantly and talked garbage all the time about how bad he was because he had a .45 ACP caliber sub-compact(one time he literally fire a hundred rounds and hit the edge of the silhouette paper twice, yeah two out of a hundred). He would constantly give me garbage in front of our friends how my .357 magnum was a piece of junk in comparison, rrrigghhhttt. And then he got his CCW permit and all hell broke loose. Well he shortly there after had to pawn his gun but that didn't stop him from showing off his CCW permit like he was somehow incredible for it. And we ended, I stopped, not riding to places together in the same car because he knew I had my Ruger with me and would mouth off about it. "Hey my friend has .357 you act like a fool and he'll end you", he said something like that one time when we were downtown picking up a friend (last time I drove with him anywhere) and kicked him out of my car(literally, we somehow continued to be friends for nearly two years after) and left him there with the person he just threatened while I raced away, granted he ran after me but had to take a taxi home.
Open carry or concealed carry, there are a lot of idiots who can't respect and appreciate the tradition and right of gun ownership. We as responsible law abiding gun owners have to to some respect ostracise these folks otherwise we'll be lumped in with them.
I figure myself as a gunowner to be a walking PR ad no matter what I do so I generally try to stay cleanly shaved, cleanly dressed even if it's just in jeans and a T-shirt, smile and be polite, and while I've got a 45+" muscled chest and 24" biceps, I do my best to never scowl or attempt to intimidate people (I'm only 5'9") unless they're justly deserving it (wanna be badasses or thug types). I reguraly work to convert people to gun ownership or at the least the idea of gun ownership being okay. I've converted four girls at my law school in that they've bought glocks, PPKs, and a 642 (Two bought 'matching' G19s, one bought a PPK .380, and another bought herself a 642 because she thought it was cute
). I will continue to work to bring more folks over to our side because the more gun owners there are, the greater our chances of being accpeted are likely.
Remember it all rolls downhill be it good or bad, I'll do my best to make sure it's good, hope the rest of you do too.
