Zero attempt to engage with one of the quintessential works of Engels on dialectical materialism (or materialist dialectics, as he puts it in the work while acknowledging Joseph Dietzgen's discovery of the same system of analysis), Ludwig Feuerbach and the End of Classical German Philosoph.
These attempts to sever Hegel from Marxism always have what feels like an oddly conservative bent, funnily enough mimicking Hegel's own conservatism that ran contrary to his often revolutionary work. I prefer Losurdo's attempt to defend Hegel and Hegelian dialectics, than to cast them aside as idealist and therefore useless, https://redsails.org/losurdo-hegel-marx/.
