Today, the Union flag on the Bank of Scotland has been replaced with a red and black flag.
The red and black flag goes from bottom left to top right, with red on top and black on bottom.
The red is the red of the communist flag, and symbolises material equality, or the principle of “from each according to their abilities, to each according to their needs”. The black is the black of the anarchist flag, and symbolises social freedom, the freedom of each individual to do as they please so long as their actions don’t cause harm to others.
Together red and black symbolise libertarian communism. It goes diagonally as a negation of nationalism and a reaffirmation of internationalism.
