I saw an old vid of bikers with a swastika inside a star of david-idk what it means?

Some bikers tended to use Nazi symbols such as the swastika or the iron/Maltese cross as a sign of their rebellion. Not so much a link to being ociated with Nazism or Aryan lifestyles (well, mostly). It started post war world two when the biker life style sorta took off ala motorcycle gangs. It was a real hard *** way of saying they weren't the same as the casual person on a motor bike.
