<<To put it bluntly, I think JH has it completely
backward: it is via domination and power that we are able to
communicate with each other.>>
Here you seem to be saying that power differentials are what make communication possible.
If/when we succeed in overcoming
capitalist domination, we will not be "closer" to some sort of
ideal communicative situation; rather, we will be engaged in different
language games as appropriate to that context as existing forms
of communication are appropriate to the existing context.>>
Here you seem to be saying that communication/"language games" will be different (but no less possible) in a context where power differentials are decreased.
Am I misunderstanding you? The two statements seem to contradict each other.
