The KKK was actually formed for the purpose of protecting women's rights iirc. There were black members in some area's and they lynched Caucasians occasionally.
edit: Still terrorism and what they did was despicable, just saying that it wasn't their original purpose.
I think he might be referring to the WKKK (http://en.wikipedia.org/wiki/Women_of_the_Ku_Klux_Klan) but its still a far fetched leap to claim that the KKK was founded for the sole purpose of protecting women's rights. That most certainly is not true.
