A middle school assignment asked students to justify the actions of the KKK

I am wondering if the teacher was trying to get the students to look at both sides of the controversy instead of just one side. My uncle by marriage lived in Oklahoma in the first half of the 1900's and he absolutely hated the Klan, he was once offered a card by someone who was a Klan member and when he said "you go to hell!" the man replied "Oh sorry, heard you was a good ole boy". However my uncle did say that the Klan was trying to get white men to stop abusing their wives by coming home drunk, spending the money that should have gone to feeding and clothing the family (ragged children), and being violent to their families by riding out on horseback with torches and pulling the errant husband out of his bed and beating the crap out of them and telling them to straighten up and treat the family right. He said they either got the fear in them and straightened up or they left the area...if they left and abandoned their family then society would take care of the family.
