The comments left at that link are simply stunning and shows how ignorant people can be on this issue.
One person stated that the flag represents slavery.
The reply was it did not , only for the dope to come back and say read the Southern declaration .
Of course the dope does not understand the battle flag was a battle flag which never flew as the official Govt flag. It was designed to distinguish between the two warring armies.
If they knew the stars and bars then they could maybe have a point , but their anger is misplaced and ignorant.
The flag known today as the Confederate flag was actually the Army of Northern Virginia battle flag that was commanded by Robert E. Lee.
