Let's hear what Blacks in South Carolina are actually looking for, not from extremists.
Nothing can eliminate the Confederate flag from this country, short of eliminating all descendants of Confederate veterans. All we are talking about here is moving it around a bit.
Practically, to what end? To calm Black sentiment and prevent retaliation? As I proposed, let's first hear from them, rather than agitators, before assuming that it would do so. And while I am not against manipulating symbols to evoke healthy emotions, there are two hornets nests here, not one. Roof said he was stirred up by the Martin case, another attempt to calm Black sentiment. (And Cohen's stated goal is not to calm Black sentiment, but to prevent the next Roof.) So from a practical point of view, what is the benefit?
If you want that symbol to lose its negative meaning, my proposal is simple: Black Southerners should adopt it and coopt it. Blacks are more truly Dixie than all the immigrants and relocated Yankees who form the majority of the "white" folk. Take the flag and say it's yours, it stands for your region, the fruits of your labor, your Christian pro-family culture, the Cross of Christ, the great non-violent civil rights movement (which came from the South), and the natural principle of subsidiarity. There's no sense living in fear of the past when you can purify it and shape the future.
This is, I think, what the federal elite (who have never forgotten institutionally the lessons of the Civil War), the Sharptons, the Democrat plantation runners ... not to mention the self-identified neo-Nazi white supremacists who are so useful to them ... are most afraid of, particularly as they begin to implement their plan to isolate all churches (including Black churches) which oppose gay marriage.
You can count on the left to over play their hand every time.
