Then there is fact of the matter about which answers are moral, and we might as well call those that aren't, "incorrect".

It seems like a waste to overload the meaning of the word "incorrect" to also include such things as "Fuck off! That doesn't satisfy socially oriented aspects of my preferences. I wish to enforce different norms!"

It really is useful to emphasize a carve in reality between 'false' and 'evil/bad/immoral'. Humans are notoriously bad at keeping the concepts distinct in their minds and allowing 'incorrect' (and related words) to be used for normative claims encourages even more motivated confusion.

No. Moral properties don't exist. What I'm doing, per the post, when I say "There are immoral answers" is expressing an emotional dissatisfaction to certain answers.
