I would personally ignore that paragraph you last quoted. This person has probably never open carried in NC and is a spectator.
There are hundreds if not thousands of people who OC every day across NC and I believe you can count the 'Going Armed to the Terror of the Public' cases on one hand involving a holstered side arm and no specific threats against a person or property. There is solid precedent backing up ones right to carry a holstered firearm and that it can in no way be construed as going armed to the terror of the public. This doesnt mean an LEO might initiate a contact or harass you. And the fact is, if you are harassed for OC, usually, the cops cant even charge you with a gun crime. Many probably don't realize that going into the stop, but they tend to throw a 'catch all' charge such as 'disorderly conduct,' etc.
Rule 1. If asked to leave somewhere by someone of in control of the property, dont argue, just respect their property rights and leave. This will eliminate most contacts with LEO's.
Rule 2. Know the law, know where you are restricted from carrying and stay within those parameters.
Opinions on OC are going to vary in the Gun Community.
1. No disrespect, but cops tend to despise any activity that isn't expressly licensed and sanctioned by the state/govt. Many despise the mere fact that 'civilians' are allowed to even own firearms. Hence, most LEO's and agencies are opposed to OC, although most seem to be tolerant in this state. Atleast in the western areas of NC.
2. There is a segment of the gun community that also follows the same logic of 'if the govt doesn't give you permission, you shouldn't be doing it.' This extends to OC. They don't like OC for the same reasons why a state licensed and permitted business doesn't like a 'black market' business that doesn't have the permits, and licenses. Because they had to jump through the hoops and people get mad when someone else doesn't do the same thing. I would ignore these people. These are the NRA 'its about hunting' types.
3. Some people play the 'tactical advantage' card and say that with OC you are going to have your gun taken from you and shot with it. Or you are going to be shot first if there is a run in with a bad guy because all your cards are showing. These are good points and very good reasons to be TRAINED and PROFICIENT with your firearm. Both in manipulation and retention. They never will bring up the fact that you might deter a multitude of crime by being a professional looking, clean cut person lawfully OC'ing a firearm for defense. I also recommend being clean cut and not looking like a bum. You might also invest in a good retention holster with a bale or locking mechanism like a GCode or Safariland if you dont have good training on weapon retention. (or even if trained)
I say OC, don't ask permission in the form of a CCW permit, even though, in many cases it might be better to carry concealed. After you do it for a while, you'll get confident. And most of the time, 75% or more of the people NEVER notice or if they do, they think you are a cop. People tend to leave you alone and you also tend to get the best customer service.
