This image was taken at the 2010 Mayday Rally in Melbourne
The people in the image are communists, I think, of the Stalinist type or Trotskyites
When people talk about the left these are as far left as you can go. Eg no ownership of private property, no national governments and many other radical things.
I once tried to join the Communists but for a variety of reasons decided not to.
Another interesting aside is both my grandfathers were killed by the Stalinists. They died at Katyn though this was not a reason I decided not to join the Stalinists.
Another interesting thing is Mayday originated not from Russia but the USA. The day is to commemorate the execution of a number of union leaders in the US late in the 19th century.
Being Communists I had to make the picture in color, red lol
