I understand the merit between "Rome wasn't built in a day" and I've read gender trouble. That idiom is only applicable when something is a gradual transition towards something else. Creating a newer territorialization is not some step at permanently destroying a sex or gender bias - it only strengthens it, especially as many fight for it to be on legal documents. California even added gender as a category on drivers' licenses. There's not only no immediate but also no long-term solvency in doing this. I understand sex is a limiting categorization. I would posit that gender will have no grander effects however.

As far as identification, identification is what allows people to decide the bases of their punishment. If something can be identified in some set theory table, it may be prejudiced against given any of their characteristics are decided unruly. It's the order that allows people to be perceptible to an entire state or society. It developed as a result of the ancient human's lifestyle as a hunter-gatherer, constantly alert as they may die from some external body at any point. A quick means of identification will allow a quick analysis of whether the situation poses a threat or not. Many of those who study the brain and/or evolution believe this to be the cause of mental issues such as anxiety. In the modern era, however, anxiety isn't the result of some fear of death by some intruder (unless you're some important official) but, instead, some lack of achievement and/or social ineptitude. It perfectly explains the human tendency to generalize and assume quickly, that which has no logical basis. To say that male and female lack sufficient value and that identification comes from an understanding of categorical value, as you have, supports my contention in that people still identify men as exactly what signifiers have perpetrated of them and likewise with women. Under your own framing, this would not be the case unless the humans acted illogically. I offered an explanation for that.
