I don’t need Marx for class analysis and I agree on being united. What I do not like is puttingn theory in front of praxis. I won’t ever say “I won’t unionize with this Marxist”, I just won’t play their theory game on their field 😎
As I said, don’t need Marx to still get to the same direction of unions, associations, cooperatives, NGOs, mutual aid, sabotage, anticonsumerism and so on 🤝
