I make the trip to Charlotte every other year since its only about 3 hours from my house here in NC... Most of Charlotte's fans are great. Friendly, quick with recommendations on things (bars, restaurants, hotels, etc.) and very respectful because they know UNCC has done nothing on a football field ever. Their stadium is small, but it's nice and easy to get to.
That said, the worst 2% of Charlotte fans are among the worst I've encountered in any CUSA city (and I've been to almost all of them over the years except North Texas, UTSA and La Tech)... Their "bottom 2%" desperately want to be relevant to the point of talking themselves into relevance based on "big" wins over other CUSA bottom feeders.
They may very well make their first bowl game ever this year and do battle with a directional Michigan in the Bahamas. If that happens, you won't have to look it up anywhere, their bottom 2% will be sure to tell everyone about it for years to come.
