I have always taken a small amount of pride in the confederate flag, simply because I'm a "southerner", and I really resent having a federal government over-ride states' rights. THAT'S what it meant to me.
Over the past few years, however, it has become known as a symbol of disrespect to black Americans.... something I never associated it with.
For that reason alone, I would never fly it, wear it, or endorse it, personally, because Jesus called us to love all people. To me, it's much like Paul said, I have the freedom to do it, but if it causes problems with others we shouldn't do it.
It's STILL not a symbol of racism or slavery to ME, because I despise the legacy of slavery...but it is to many others.... so I won't do it, no matter how proud I am to be "southern"....
