This too is dumb. Just because you love the word meta- doesn’t mean you have to use it everywhere. There’s already a sharp distinction between moral codes and moral systems. And until you have to build your own moral system, you won’t know what the hell you’re talking about. It’s why you set up all these dumb attacks against strawmen moral systems. It’s been literally centuries since anybody serious about moral theory had any god on the playing field. And circularity? Yawn. As you bloody well should know, circularity is to be avoided at all costs. If you’re yammering on about it it’s because you aren’t familiar with any moral theories.
Stick with your resolution to avoid meta-ethical reasoning, since yours sucks.
