Of course, its your own choice entirely what you do. No one will be held responsible for your actions but you.
But, its your right to openly carry a firearm is you so choose to do so, and I hope you would be able to do so without fear of being illegally prejudiced against for doing something perfectly legal.
Just be polite to people in general(no matter if you OC, CC, NC) and your life will usually be rather non-eventful.
If the Police detain or harass you be simple in your choice of words(if you so choose to break your right to remain silent) if they are willing to listen, you will probably walk away from the situation. If they aren't, its really not your fault if they commit an illegal detention and/or arrest.
If you read all the stories here from the North Carolina page, you'll find the vast majority of people's experiences are essentially non-events. But, life happens and we have to deal with what happens.
