When I first started tracking the League of the South there were people who really didn't want to acknowledge that they were racists and came up with all sorts of rationalizations to deny it. I think however, this essay by Michael Hill will settle this question once and for all:

Hill's essay both makes it clear and explains at length his racist ideas. He believes that the races, as popularly thought of, come from the sons of Noah, Shem, Ham, and Japeth, from his interpretation of the bible. White people are held to be the sons of Japeth. Hill believes that God favors white people.
After his biblical arguments for racial separation he has a fairly elaborate exposition of his racist views. The following is a sample quote:
"Our white European-American ancestors had no trouble enunciating the obvious truth that Western Christian civilization was superior to all others. Moreover, they had no hesitation about defending it, as their God-given patrimony, against those who would denigrate or destroy it. Just a century ago, our civilization was still distinguished by a robustness and self-confidence born out of a realization of the natural superiority of the West and its ways. None but the most crack-brained utopians believed in social, political, economic, and cultural equality, nor did they believe in the equality of the races in intellect and accomplishment. Unfortunately, the present century has witnessed the old order turned upon its head."
