There are many symbols that originally meant one thing and have been bastardized over the years. The iron cross was a German military medal going back to Napoleon's time, may even have a history before that. The Nazis, white supremacists and outlaw bikers have ruined since then. I remember going to a car show with my older brother and sister in law when I was probably 6 or 7. I bought a small iron cross and thought it was the coolest thing ever.
