That’s why I don’t think it necessarily follows that gender itself is a product of oppression, which also puts into question whether it should be or will be abolished/wither away (not exactly the same thing for some abolitionists, but not all). The premise of the essay is that gender can exist without an oppressive structure. It also means it doesn’t automatically follow that abolishing gender (in any way) will also destroy the oppressive structure built around it and the answer must be found somewhere else for proper praxis.
In reference to my previous comment, by gender "withering away" in a communist state, I don't mean gender will not exist, just as race won't disappear. I mean the distinction between class won't be really relevant anymore (at least relevant in the case of exploitation and discrimination, though perhaps more in a far future society depending on the path we take (such as becoming machines or maybe becoming a gestalt consciousness)). A communist state will likely be in the distant future, a society we can only predict under science fiction. I imagine technology, social relations, cultural and social norms will evolve to a point we may not be able to perceive very well today. I imagine that we may have the ability to change our DNA, or maybe go through transhumanism and become cyborgs/machines, etc. The concept of gender may not be as relevant because people will be able to easily change to whatever they are comfortable with using future technology, and there will be cultural acceptance of everyone. There won't be a denial of trans/gender-fluid/non-conforming people, but it may be ubiquitous that the distinction and class differences/exploitation between people won't exist as it does today. Before then and when we are still developing in the early stages of socialism, we won't be "abolishing" or "withering away" gender, nor will gender completely not exist.
As for now, I agree that so-called "gender abolition" is irrelevant and out of scope at this time.
I imagine these people are the same or close to those who say "they don't see color".
