he examples of “incoherent” concepts you gave are a mixed bag of concepts ranging from the well defined but false, to the well defined but ungrounded, to the ill defined. If you want to say what specific kind of incoherence “morality” has IYO, feel free.
You seem confused about what argument CuSithBell is arguing. The argument is not that morality is fundamentally incoherent or meaningless but that most definitions of it fall into those categories and that our common intuition is not sufficient to have useful discussions about it, so you need to supply a definition for what you mean. So far, you seem to have refused to do that. Do you see the distinction?
How are motivations relevant to where burdens lie?
Really? So, what about here?
