Zzyym's parents and doctors attempted to 'fix' them via multiple surgeries during childhood. There is no way to tell now what Zzyym's reproductive abilities might have been had they been allowed to develop naturally. They might even have been one of the rare intersex people who could produce both types of gametes.Unless Zzyym produces BOTH functional eggs and functional sperm, they are either male or female, not both. They may very well have ambiguous or mixed sexual characteristics, but sex is still actually binary.
Also, nobody refuses to acknowledge that some people have DSDs. The question, however, is what do people with rare and deleterious medical conditions have to do with transgender ideology?
Also, I think it's important to note that some people are completely unable to produce gametes. If we use gamete production as the standard for sex designations, they would be considered sexless.
