I guess you don't have time to read the disclaimer in bold letters on their site?
Disclaimer: This page or anyone involved in its creation, or members of reenactment groups listed here, are in no way affiliated with real, radical political organizations (i.e., KKK, Aryan Nation, American Nazi Party, etc.) and do not embrace the philosophies and actions of the original NSDAP (Nazi party), and wholeheartedly condemn the atrocities which made them infamous. May the victims of this unspeakable horror rest in peace. As we portray the German combat soldier, we are only interested in recreating his daily life, furthering our understanding of what it took to be a soldier, and at the same time having fun reliving history. We honor the men (and women) who really experienced the war, and we salute their courage and loyalty to put their lives on the line in defense of their native soil, no matter what nationality or government. - Willkommen! 5th SS Wiking German Reenactment Page
That's OK though, I understand political blindness.
