Neuter is an unlabelled experience similar to neutrois or gender-neutral. It's different in the sense that one refuses to define oneself under a gender term.[1]
Yet neuter is described as a grammatical gender parallel with/to masculine and feminine,[2] it's not commonly used as a gender identity or experience, therefore neuter is equiparable to both none and neither.
It can also be a translation of the Portuguese neolingual term neutre, which is an othergender balancing positive, negative, and null, hence it's adherently a gender quality, that is essentially not presentational.[3]
