Evidence that these guys are white supremists is fairly scant, and I don’t consider the Southern Poverty Law Center to be a credible source.
There is this from their website that I find troubling:
"Americans will fully recognize themselves as a people, not merely citizens or residents of a country, but a people bearing a unique national interest rooted in our heritage on this continent. Our people, born to this nation of our European race, must reforge themselves as a new collective capable of asserting our right to cultural independence. The LIFE of this nation, unique among all others, will be defended."
