Consider myself pretty much of an absolutist (that's not a vodka drinker, by the way - though I've had my long week ends, heh, heh) when it comes to the bill of rights. That obviously includes the 2nd amendment. I had a CCW on the mainland and often packed. Having said all that, I'm against the principle of open carry, simply BECAUSE of the reactions of other folks. I've tried to live my life being reasonably considerate of other folks feelings - even if I don't understand or agree with them. I would never "stare" at someone on an elevator because it can be intimidating. It's just common courtesy. So, unless I'm in the wide open spaces (or at the gun range) I always conceal. NO ONE has EVER seen my concealed-carry weapon. I consider it a courtesy.
Regarding the principle of carrying any weapon, concealed or otherwise (and any referral to "wild west" situations which might ensue) I have found that those who carry are much LESS apt to get into an altercation BECAUSE they know the consequences of the use of deadly force. I have discussed this subject at length with others who carry. While I have entered premises clearly marked "no concealed weapons" while carrying (e.g., Starbucks of another place and time) I specifically NEVER went into any bars, entertainment venues, etc. where fights seem to erupt upon occasion. I just wouldn't do it.
Carrying a deadly weapon is an awesome responsibility. If anyone doubts their own judgement (as I would in a bar especially after social lubrication) DON'T carry - concealed or otherwise.
I've made a personal decision not to even own a weapon in Hawaii. CCWs are virtually impossible to get here. Too much hassle and worry (e.g., possibility of theft) to keep a weapon in the home. I DO own a ball bat if anyone should attempt to enter, uninvited while I'm home, heh, heh. Otherwise, they can have my cheap TV and clock radio. They won't find a gun, though.
