Another "moonlight and magnolias" myth:
"Around here the really old people tell you that after the Civil War, the Klan wasn't about racism, it was an order of "knights". They were about the only law other than the yankee occupiers. If a man stayed drunk and didn't take care of his family, the Klan would visit him one night, maybe rough him up, let it be known it was in his best interest to work and support his family."
What insultingly inane drivel.
The Ku Klux Klan was formed by hardcore, unrepentant Confederates, notably the brilliant cavalryman Nathan Bedford Forrest, to suppress blacks from exercising their newly-acquired rights, primarily voting. It used terror in all forms, from dressing as ghosts (hence the "sheet" uniform) to scare the superstitious ex-slaves to rape, beatings and lynchings.
These allegedly non-racist "knights" grew so violent that even their most prominent proponent, Forrest, quit the organization in disgust. It faded until D.W. Griffith's racist film, "Birth of a Nation," which portrayed blacks as lecherous beasts slavering for white girls to rape, came out. It legitimized the Klan, which grew rapidly in the '20's and was responsible for most of the beatings, lynchings and murders of the Civil Rights era of the '60's.
For those who actually want a clue, look into the murder of Violet Iuzzo (run off the road by Klansmen for driving civil rights workers), Goodman, Schwerner and Chaney (civil rights workers released to the Klan by the local PD; beaten, killed and buried in a coffer dam, made into the film "Mississippi Burning"), and the bombings in Birmingham, Alabama (6 little girls killed in just ONE church bombing).
That said, if a girl wants to wear a Confederate flag, the First Amendment should protect her. Period.
I fly the Stars & Bars; i.e., the First Pattern CSA flag, on the birthdays of R.E. Lee, T.J. Jackson and Jefferson Davis. I have no more use for PC fascists than I do for Klan apologists!
