I think...that you're wondering..how I overcome any and all logical challenges to a given moral schema. The short answer is that I don't. I accept the limitations of those things I advocate for. The possible and existential ambiguities. I think that's the only honest or genuine thing to do.
So, when I think about moral facts - I think it's a necessarily small set. There are more things...and many more things...in the world...than moral things. This is sometimes called minimal or skinny realism. There is a large set of moral assertions. The vast majority are false in-fact. Some portion are ambiguous. There is at least or could be one (or some small number) that are true..and true-in-fact. In my experience, the moral landscape is so cluttered that it's often useful to do even a brief one by one about moral assertions and facts in order to pick out subtle but consequential differences in a given schema. Pick some specific moral assertion - I'll just tell you what I think...and the whys can be easily drilled down..or not..in which case..I'm in error..and the assertion to fact was not a fact, in-fact. Objectively speaking
