Not sure why her reversal of position would make her a FF now. It took a massacre for her to switch her position away from a battle flag that flew under a vicious government and was later made famous by the Ku Klux Klan.
Sorry dude, but there wasn't really a legion of Republicans or Democrats adamantly calling for its removal before this. People give Truman a pass for being a huge racist early in his career because he eventually did the right thing. People give LBJ the same forgiveness for his sh*tty civil rights record as a Senator because he came around and ended up supporting and signing the CRA. Robert Byrd - who literally was a Klansman - is more or less completely forgiven because he said sorry!!
I expect the same treatment - at least on this issue - for Haley, Graham and everyone else calling for its removal.
Everyone sane thought it was ridiculous that they still had a flag from their capital building in the 1990s, and didn't completely remove it from the grounds with their moderate hero compromise in 2000.
