When the KKK members get hoisted up on flag poles over state capitals, now that would be a great conversation starter!
The issue with the Confederate Flag (and/or Battle Flag of the Army of Northern VA, which is the one typically flown, which is so Ironic to me when those flying the "Stars n' Bars" are popping off about heritage and "history") is not that it's being flown, but rather it's being flown on Govt Property.
You want to wear some clothing with it, put it on your car, fly it off your front porch, I for one don't give a crap (in fact, I would like to thank you for helping me identify the idiots that much easier). But, flying the flag of a "nation" that rebelled and fought a war against the United States Govt, to honor that by flying the flag on Govt property of the Nation that they hated, just seems "weird" if nothing else. And for those who don't think the flag originated and is based from a government founded nearly exclusively on the concept of slavery and racism (and their desire to keep it), should spend an hour or two reading the secession documents submitted by every Confederate State.
From the VP of the Confederacy, Alexander Stephens detailing all the differences between the US Constitution and the Confederate Constitution, spells out it quite clearly:
"Our new government is founded upon exactly the opposite idea (from the US Constitution); its foundations are laid, its corner- stone rests, upon the great truth that the negro is not equal to the white man; that slavery subordination to the superior race is his natural and normal condition. This, our new government, is the first, in the history of the world, based upon this great physical, philosophical, and moral truth."
