I was responding to a slightly different situation: you suggested that sometimes, considerations of "correctness" or "right/wrong" don't apply. I pointed out that we can get a sketch of these notions for most things quite easily. This sketch of "correctness" is in no way intended as something taken to be the accurate principle with unlimited normative power. The question of not drowning the normative notions (in more shaky opinions) is distinct from the question of whether there are any normative notions to drown to begin with.
