For example, reading the arguments in Street’s papers (see for example, “Objectivity and Truth: You’d Better Rethink It”, or the reply to Copp), one can say that any version of moral realism that is not committed to the claim that immoral behavior is necessarily irrational, is not targeted (it is not even considered a form of realism by Street, but it is by the definition in the other thread, at least as I think is property interpreted).
In my assessment, there are morally wrong behaviors, and whether a behavior is immoral is a matter of fact, but while immoral (i.e., morally wrong, unethical, etc.; those are synonyms) behavior is nearly always irrational, it is not always so (probably not even in the actual world). The DD isn’t even targeting any view with those properties
