Ultimately you have to do a little soul-searching and self-education. Are you up to it? It would be good for you to have some answers at the ready if folks -kids and adults- question why you are wearing the Battle Flag buckle. It's the "teachable moment".
Here's some things to think about:
1. I assume that what you have is really called the Confederate Battle Flag (CBF).It is only one of many flags used by the CSA and is not the national flag, although its design was incorporated into the CSA's 2nd and 3rd National Flags.
2.The Battle Flag is also known as the Southern Cross - since it is derived from the x-shaped cross of St. Andrew, and used on the Saltire flag of Scotland - whence came many of the Southerners. And attests to both an ethnic and religious heritage.
3. You will readily see that in a battle, with gunsmoke and fog around, it is easy to confuse the USA "Stars & Stripes" and the 1st National CSA flag- "Stars & Bars", especially if there's no wind. So the Southerners needed a distinctive banner particularly for use in battle situations. So, the battle flag should be used to honor the exceptional valor of the soldiers of the South - a fact that is universally acknowledged. It was so well defended that to capture one in battle just about guaranteed a Congressional Medal of Honor.
4. Also, you should know that all men who served honorably in the armed services of the CSA are, by mandate of the US Congress, the Pentagon, and the Veterans Administration, are to be accounted as US veterans and accorded the same honors as all US Veterans. This includes military gravestones and public monuments for them. Men (and women) who served in other "unpopular" wars, especially Vietnam, appreciate this aspect. The Battle Flag represents patriotism and loyalty to family, home, state and country. Only to the extent that the South was invaded illegally and unconstitutionally, does it represent defiance and resistance. (And that's a whole 'nother topic.)
5. Teach folks that when the Battle Flag again becomes a familiar feature of the civic landscape, it will cease to be a bogeyman, and will re-assume its role as a recognized symbol of a distinct region and honorable heritage.
6. You should know that the Confederate states and its citizens were the ones which wanted to uphold the original US Constitution and the Founding Father's vision from the time of the 1st American Revolution. Wearing the CBF represents an appreciation and expression of your Constitutional civil rights- especially freedom of expression. If they don't teach and support this at your school - why not? Are they phony hypocrites, or supportive? Teachers and even principals sometimes need this lesson.
7. You should look into your own lineage and see if you are descended from a CSA veteran, and have a family link and honorable tradition to uphold; and join the Sons of Confederate Veterans or Children of the Confederacy. ( Or United Daughters of the Confederacy if you are female).
By wearing the CSA's Battle Flag, you are now joining a righteous crusade. It deserves rehabilitation from those who have exploited it - from the KKK to the NAACP, and this can only be done by brave folks who educate themselves so they can educate others. You might get criticism from ignorant persons , so either educate them or ignore them. Be strong. Stand up for your rights and Southern heritage. And the Confederate flag design just looks great, too.
