We dont have to decide because the National socialist constitution was already written by Hitler, and his comrades. Im talking ofcourse of the 25 points.
Indeed the 25 points were written but let us no forget that the Reich itself had an interesting dynamic history from the Night of the Flying Knives to Hitler's speech at Platterhorf in which he said "Race and Volk are not the same". Out of such events deep divisions within the party have given rise to various interpretations. You are right about Rockwell though. He and Cohen (er I mean Collins

) ruined the party in America and associated themselves to much with the WASP supremist KKK. I myself am not NS (or white for that matter) but there are some good lessons to be learned from the Reich.
