We delve into the sheer impossibility of feminists working with the political Left, overwhelmingly due to the door being slammed by the Left itself. By the Left we mean socialist groups and communist parties, not liberal or rightwing Labour parties i.e the radical leftwing who have a vision to liberate humanity (given that feminists seek to liberate women). It is difficult to get across just how hostile the Left is to any women wanting to organise as women, who believe women are oppressed on the basis of sex, or simply want to highlight and tackle male violence. We provide our reasoning as to why the Left is so hostile to feminists, why some feminists on the Left still think it's possible (typically because they're married to leftwing men they wish to view as nice / kind), and give some examples of women being expelled, ostracised, and attacked, for simply pointing out male sexual violence or wanting to organise politically as women. We also discuss how today's Left is a collection of defunct sects either having been taken over by, or looking to be taken over by, anti-social men who want their own personal fiefdom, which goes someway to explaining why the Left is so beset by sexual scandal. At the end we issue a challenge: a leftwing gender critical feminist should run the experiment of joining a socialist or socialist-leaning group, announce her politics around Trans, bring up male violence, and offer her analysis against prostitution and surrogacy, then report back as to how long she lasted before being ousted.
