In this case, it does.
Allow me to elaborate. Yes, we know more now about anatomy and medicine then 1000 years ago. A good movie that illustrates this is The Physician -
https://www.imdb.com/title/tt2101473/ - it was against religious doctrine to desecrate a body. However, even in those times no one could dispute that there were no more genders then male and female.
The fact that only two genders exist has been established for millions of years. In fact, lets go back. You have your parents, your grand parents, your great grand parents, etc. This goes back forever. Back to when we were neanderthals, back when were monkeys. Even back before that. You are here, because every single entity in your ancestral lineage was able to produce offspring, because every single one of them knew consciously or instinctively that they needed to reproduce with a member of the opposite gender. You can go backwards with this right up until we get to the beginning of mammals.
You are the first generation of a lineage that has been produced by exclusively by males and females since the fucking dawn of mammalian life on earth that believes there are more then two genders. Hundreds of millions of years of evolution that produced exclusively males and females of a million different species, and now, suddenly, in the last few years, it surfaces that there are 70something genders?
If someone wants to be transsexual I'm fine with that. I don't approve of it and I think it's gender dysphoria, but those are my views. I will probably not refer to them by whatever pronouns they decide they want to use, and I will simply "call 'em as I see 'em". If they make a convincing woman *when I first meet them*, i'll call them she, otherwise it's just a man with tits much like the two in the article are just women with beards. What I will not do, is spit in the face of evolution by pandering to made-up genders such as "non-binary".
