When the Bolsheviks took over Russia in 1917, they eventually spread across the world to promote their concept of paradise. How they were treated varied from country to country. While some welcomed them, others forced them into a entity of legal discourse. In England, they were not tolerated at all. Any group outside of Labour and Tory was marginalized as much as possible. The political groups thus marginalized away from any real power became known as factions. A Red Factioner is someone from England who is in support of Marxist principles of governance.
That bloke there thinks that the Queen is one of the Bourgeois! Bloody Red Factioner he is.....
