The problem comes in when the "gender-non-conforming" label eclipses the meaningful, important part of someone's identity they lived their whole lives with.
My sense is that, for a lot of lesbians, being gender-nonconforming is a minor (and not even necessarily existing or embraced) part of their sense of self compared to being a lesbian.
I'd actually suggest the opposite for Lister. She consciously chose to live her life in a way that was absolutely contrary to what was expected of a woman of her time and of her class. Whether that was because she was a lesbian or vice versa, we can't say. A straight woman of her time and of her class could have lived in precisely the same way, absent her lesbian relationships, and would be just as remarkable an individual in retrospect.
