Fair enough, unless by "More traditional" you mean "On government property" in which case there is a fundamental difference.

Also, there's a difference between "Offensive" in the sense of unpleasant and "Offensive" in the sense of threatening. I don't think Southerners will feel threatened by that installation. I do think minorities can feel threatened by the display of a confederate flag, and I don't think that's unreasonable, even though I accept that not all Southerners mean it as a threat.
