I think you're taking that statement quite out of context and extrapolating it into an argument against math and logic. By saying 'binary is bullshit', they are making the argument that gender is a bimodal distribution, and that forcing it into a pure binary model is oppressive (not to mention counter to much evidence). Certainly in the gender distribution, the two peaks may represent so many people that it is useful to name them, just as it is useful to name many strong probabilistic phenomenae. Is the weather report that it will rain certain? No, but I'll prepare for rain. I think we'll agree on that. But many people fall outside of the bimodal peaks and are actively discriminated against by people who do not believe there is a distribution in the first place, or who believe that if you are not sufficiently close to one of the peaks that you are an unfit human being. This is why I think you're taking it out of context. You are clearly not the target audience of that statement. You understand that the two mainstream gender labels are, as you say, 'useful' and 'practical'. You understand that '1' can represent many voltages. Labels are useful, as long as you understand the level of certainty they represent. The target audience of that statement believes they are the only thing, period (taking a simplistic view), or who make a value judgement based on how close one is to one of the bimodal peaks (taking a normative view). Certainly I don't represent everything you'll read that's said or written by advocates for people with different genders, but there is illogic on both 'sides' of the arguments on gender and sexuality. Here's how I look at it. Regardless of the illogic, which side is more harmful? The side that is making value judgements based on faulty evidence and using those to propose and enforce sometimes tremendously painful rules on others, or the side that is sometimes making illogical arguments in an attempt to be accepted by society?
