Platypus describes its own approach to Marxism as a "synthesis" of Trotskyism and Frankfurt School Critical Theory, via the two more recent approaches of the International Communist League (Fourth Internationalist) and the reinterpretation of Marx's critical theory by Moishe Postone. However, Platypus sees its role not in formulating positive practical political positions or offering analysis, but rather "hosting the critical conversation on the Left that is presently lacking." This includes inviting speakers with extremely varied and opposed views as panelists debating issues in public forums, and publishing writings from widely differing viewpoints on the Left in The Platypus Review. The degree to which members of Platypus have offered definite statements as public speakers or writers, they have been restricted to critiques of the existing Left.
