To be absolutely clear, my post is about the way academic philosophy happens to organize a certain debate

Note that "the way academic philosophy happens to organize" debates about ethics and morality should be taken with a huge grain of salt. Most people who engage in moral/ethical judgment in everyday life pay very little attention to moral philosophy in the academic sense.

In fact, as it happens, most of the public debate about ethics and morals takes place outside academic philosophy, and is hard to disentangle from debate involving politics, law and general worldviews or "cosmologies" (in the anthropological sense).
