Labor skinheads and neonazi skinheads.

I was so sad when I discovered the Hammerskins were a thing (a White Power band inspired by Pink Floyd's Waiting For The Worms, but without the irony, with a corresponding militant movement). The Hammerskins took their logo:

From the Hammers banner from the movie version of Pink Floyd's The Wall

Which means when I reference the Hammers in parody of white power movements, I risk being associated with an actual white power movement.

If they had balls, they'd call themselves The Worms.

<looking up to make sure The Worms isn't a social movement yet>
