Originally the klan wasn't even against blacks. They were formed to "visit" men that didn't take care of their families. Some men were drunks that wouldn't work and beat their wives and children. The klan would pay them a visit to adjust their behavior. The klan would go to a white man's house just as soon as they would a black man. 13 do 50 was just as true then as it is now. They found themselves always, always, always having to visit nigger houses!  These men in the klan had grown sick and tired of seeing women and children with obvious signs of being beaten and starving! Even when it was black women and children!  They didn't originally start out lynching anyone! Just let them know that their behavior would not be tolerated. Men should work and support their families and not be getting drunk and beating the shit out of them. If these men didn't change their ways then the klan would show them just what it felt like having the shit beat out of you! Over time the klan was taken over by people that just wanted to lynch niggers. Even at the beginning of that it was only the niggers that raped white women!
