To clarify, I'm an anarchist. I don't think the state should exist, period, and I think it's self-defeating to try to impose communism via the state.
But more to the point, my original comment was in response to your analysis of OP's questioning of China's alleged human rights abuses. I was interested in your dialectical thinking because I hadn't seen it applied so clearly before and I wanted to use it as a learning opportunity. I'm coming away feeling more educated, which I'm grateful for. But I'm also not convinced your analysis allays worries about potential abuses mentioned in the OP, and I wanted to say as much. So ultimately, I'm not really arguing for anything specific, mainly because I don't pretend to have concrete answers. If anything, I'm arguing for greater political imagination. Liberal democracy is obviously not the answer, but I'm not convinced an authoritarian socialist state is either. So how could we build on the works of Marx and other communist thinkers to come up with a way to implement communism that avoids the pitfalls you yourself have admitted are potential problems with a communist-party-controlled state?
