It would, however, be sensible to object to sites where monuments to the Confederates still stand. That doesn't have to be the whole South.
Our focus in these times shouldn't end with pulling down the Confederate flags (whether national or battle flags). Or even pulling these symbols out of state flags that contain them. It would be a shame to stop there.
Along with the flags, all those monuments to slavers, to segregation, and those who fought for such things should be pulled out of public places and transferred to museums.
And in every one of the museums that host such things, it should be made clear that these are relics of a time when we permitted treating people in ways that should not be permitted. These are relics we keep not for any reasons of proud heritage -- because it is most definitely not proud -- but to remind us to be vigilant lest we allow ourselves to slip into such despicable errors again.

It'd make that sweet tea even more refreshing.
