Welcome to OCDO! We welcome people from all walks fo life here--as long as you are pro-OC, and pro-RKBA. All the other stuff doesn't really enter into the equation, as long as you are law-abiding, proficient, and safe.
There is a "Pink Pistols" branch in Charlotte. I don't know how active they are, but they have a very good reputation nationally, and from my limited experience with their members, are some VERY knowledgeable, friendly, and well-spoken people. Here is their contact page:

The members of this group set up a LOT of "range days" when the weather gets warmer--so if you watch the forum, you should see the "range day" planning threads start up again soon. Charlotte is sort of outside the "hot areas" for OCDO in NC--most of our really active members are in the Raleigh area, or in the East. There are a few active members out in the Western part of the state, but not many "vocal" members down in the Charlotte/Mechlenberg County area. I don't know why that is...
I'm sure you will be welcome at any range day event we have. OCDO people are a pretty accepting crowd--if you have guns and are enthusiastic about firearms, then you're "part of the club" pretty much instantly!
Welcome, and stay safe!
