>>146188It's kind of a nonsense distinction. The 19th century differed substantially from the 20th century; there were certain issues that came up during the 1900's that classical Marxism never had to address, so calling yourself an orthodox or classical Marxist or whatever in 2021 doesn't really mean anything. It doesn't indicate where you stand on issues like two-stage theory, socialism in one country, revolutionary nationalism, etc., let alone more modern debates like third worldism, free trade agreements, service-based economies, climate change, etc.
