The symbol of Italian Fascism, the fasces.
It is a bundle of sticks with an axe blade at center. Although it's sometimes used in heraldy, in modern context, I would give it a 10.
The Iron Cross(distorted crusader's cross) is a widely used Nazi symbol, but brands like Independent use it and so do many biker gangs, which may or may not be fascist or Nazi's. I would give this a 4 or 5.
The Celtic cross has pretty much been nazified. Although maybe some Celtic churches use this cross, I would definitely give the Celtic cross a 8.
Nordic Runes are used by some Neopagan groups, but mostly by nationalists nowadays, who sometimes are Neopagans. I give this an 8.
