I think that the conflict here is that you are asking which term nobody9999 prefers to be used to describe a group of people similar to them on a certain set of axes, whereas it seems that nobody9999 would prefer that there not be such a word because they'd prefer not to be grouped on that set of axes at all.

On a personal level, this reminds me of my own struggle to identify with the term "agender". At best, it's not incorrect. But it describes an aspect of myself that feels irrelevant to whatever context it's brought up in, almost to the point of being a category error. I am currently wearing a black shirt. Does this make me a black-shirt-wearer? Well, yes, but this tells you nothing about who I am. Better to describe me on a relevant axis: I am an engineer. I try very hard to be kind to everybody no matter what I think of them. I am an optimist. I enjoy sour beers. All of these are more relevant than asking what gender I identify with, because the fact of the matter is, I don't.

Extrapolate that to the disagreement between you and nobody9999 if you find it useful; I may have misunderstood the debate or nobody9999's point entirely and make no claim to represent their views.
