I'm from Ohio and My moms family is from Kentucky and my Dads from Mississippi and I'm proud of my southern heritage. Recently I bought a large Confederate flag at a Flea market and hung it on the ceiling of my room. I go by the motto heritage not hate. I have a few black friends who aren't bothered by it but a white friend of mine thinks its offensive and hates me now. So do you find this as a symbol of hate or a proud heritage?
EDIT: To be fair as I said I also have a American flag hanging right next to it to honor my ancestors who were killed on both sides
The flag does more than just represent a southern heritage, it represents a specific movement and time, and probably not the best one to be proud of necessarily. Which isn't to say that you should in any way be ashamed of your heritage, but it might not be their greatest moment to fly a symbol of.
The flag itself doesn't offend me, to be honest, but it does carry a lot of historical weight to it, which would be hard to entirely dismiss. The flag strongly represents a time when a group of people were dissatisfied with not being given their full way tried to seceded from the country; a major reason for the secession was that southern landowners didn't feel represented in congress because their slaves didn't count as much as freemen when determining congressional votes, so they decided to violently try and take half the nation with them.
To try to divorce the Southern Confederate Flag from this notion ignores a lot of history and is far more offensive than the flag itself could be. It gets more frustrating when some people, not including you necessarily, fly this flag, ignore that history, then further rebuke less violent dissonance than the flag represents with rhetoric such as "If you don't like how the country's going and don't obey what's going on 100% you're a terrorist, and get the f- out.". If you try to steal their property with force of arms the irony is usually lost too.
To be honest, while the American flag doesn't represent the south exclusively, it does do a somewhat good job of representing it, if you don't mind it being a representation of the north too. I'm not an expert on state flags, but you might find some of them too, if you want ways to fly your heritage's colors without the same negative connections.
In either case, you're free to fly whatever flag you want, but just please don't ask people to ignore the history around it, and if they do get offended, try to be patient and reasonable, within some reason. If they're trying to force you to get rid of it, they've well beyond overstepped their boundaries.
