Insofar as they can be called arguments at all, they rest on moral -- or at least, "subjective value", which some would see "moral" as a subset of, with other subsets including "aesthetic" and probably some others; these distinctions are not well-defined and, ultimately, I don't think actually meaningful -- bases.

To the extent something can be reduced to cause-effect proposition, it is a fact question, not a value question. Morality consists of the space of value questions. It may be necessary to answer a fact question to address a value question in a particular value framework, but ultimately a question that can be reduced to cause-effect propositions is not a moral question, but a fact question (which may also have utility in addressing a moral question.)
