The idea that nonbinary = genderlessness is still a massive reinforcement of binary surpemacism. The idea that if you are not binary, you must, simply must lack a gender or care nothing about your gender is simply a belief in the idea that genders outside manhood and womanhood are impossible or unimportant. The idea that "there can only be two genders". I see this view parroted around by binary people all the time, particularly trans health organisations which is extremely damaging for enben (both genderless and not) seeking medical care and lifesaving gender affirming care. It still subscribes to the idea that enben who are not agender simply don't exist, and that if we care about our genders, we also don't exist. I as an enban am allowed to care about my gender just as a man or a woman would.
I am nonbinary, and I care about being nonbinary. I have a gender, and my gender is under the vast nonbinary umbrella. Nonbinary is not always non-gendered. Not even most times.
