Then why do Democrat politicians do it?
You do realize it was a Democrat governor of South Carolina who first raised the Confederate flag over the state house don't you? His name is Ernest Fritz Hollings. He used to be the governor, he put it up. Later he became a U.S. Democrat Senator representing South Carolina.
But he wasn't the only governor of our time that celebrated the confederacy. Bill and Hill Clinton did too while he was governor of Arkansas. In 1987, while governor of Arkansas, Bill Clinton signed Act 116 that stated “The blue star above the word “ARKANSAS” is to commemorate the Confederate States of America.”
But then again one person Clinton portrayed as his mentor from Arkansas was Senator J. William Fulbright, a proud segregationist!

But speaking of Arkansas, another famous Democrat Senator from Arkansas, was Al Gore's father. He too was a segregationist. He was in office during the vote of the Civil Rights bill and voted against it like most the Dixiecrats. (Southern Democrats) And just a stone's throw away in West Virginia was Democrat Senator (Sheets) Byrd....not just a member of the KKK but one of their grand wizard types. Ole President Johnson was indebted to the Republicans in getting the Civil Rights Act passed and made that publically known as the Dixiecrats (Southern Democrats) tried to thwart it every way they could muster.
I agree with those who think the Confederate flag should be in a museum. But what I have a real problem with is the revisionist history being portrayed by those on the left. Either be willing to tell history honestly and stop the revisionism or shut up and sit down.
