Yes meta-ethical constructivism. I've read some of her work. For me, it has been either hit or miss and her focus on identity steers too much into subjectivism.

Here, I try not to make any assumptions, not even about rationality. Only that by valuing freedom and reason can we get moral principles. That's what is good about valuing freedom, you don't have to care about what people want, but only recognize that they have wants.
