>>2289365Dear enemy, I opine that the relative ethical underdetermination of marxism (besides "overthrow capitalism/build socialism") is mainly to do with the fact that Marx & Engels put a lot more effort into the "descriptive" aspect of their worldview.
To some degree they even argued that it wouldn't be possible to provide more than a broad sketch of what socialism should look like.
This in large part is what allows to be such profound enemies despite both being students of marxism. We may both desire socialism, but the ultimate aims that we wish for socialism to achieve are fundamentally irreconcilable.
