Why are they flash points? My goodness, have we gotten to the point where our collective feelings are so fragile everything hurts us? We've become so worried about hurt feelings that we're losing sight of the bigger picture. Those statues are of men long dead who fought in a losing cause.
As KN said, it's part of our history. Why not look at them and if you disagree with having them smirk and say "You lost" as you walk by. Those who can agree that the cause was wrong but the men brave can think what they want. White supremacists can think what they want. They have that right here in the US, we all do.
