1866-1867, their first actions were against Reconstruction and carpetbaggers from the North

Not even close, Q.

The KKK primarily operated directly against Blacks exercising their civil rights, and returning them to de facto slave status. I see you also subscribe the the "carpetbagger" myth. You need to bone up on modern historical writing that isn't tainted by "Lost Cause", "reconcliation", and "redemption" fantasies, or neo-Confederate bullshit.
