CFLarsen, well you're scandinavian so I am sure you know some of the symbols that, been worn nazis and similar groups, have gotten a missunderstood,or altered meaning in the eyes of a lot of people.
Symbols such as, of course, the Swastika, which does appear in many elderly cultures.
The Suncross, The Sunwheel, ancient symbol, appears on viking runes and jewelry as well as in other ancient cultures.
The Triscelon, a three-legged version of the swastika, originating from ancient Greece.
VargHaken, an old pagan symbol originally used to protect against werewolfs. In modern times often used by the group WAR (VAM in swedish), White Arian Resistence.
The Celtic Cross, originating from Ireland and Scottland, often used today by nazigroups and racists of the White Power persuasion.
The Gryphon, old mythological symbol, frequently used Swedish nazirelated groups.
Thor's Hammer, the symbol of the Norse god Thor, God of Thunder.
Very often worn by swedish nazis and nazibands singing about the glory of the nordic arian race.
A famous painting from the 18th century had both the symbol of the hammer and the swastika, Hitler loved this painted and in his crusade is said to have been "artistically inspired" and influenced by it.
When Sweden, Great Britain, Germany where in a sort of "competition" of who were the most "viking like".
These above are a few of the symbols that before the stain of Hitlers era did carry a nobel and patriotic if not poetic meaning for many.
