On Twitter, a YouTuber with a large amount of followers made a thread about how the helicopter gender is valid, and it is unreasonable to disagree with the identity of a person who seriously identifies as a helicopter gender. 

Most of the replies agreed with this Twitter user but one of the replies was less accepting, saying that if a person thinks they are a helicopter, that is a delusion. Another person then replied to that person informing them about 'Xenogenders', and included a bundle of links to a site called LGBTA wikia, which documents thousands of different 'Xenogenders'. One of them was a gender where a person identifies as a cat, another was a gender where a person identifies as a jet airplane. None of these were labeled as satirical by the Wikia in question, but genders meant to be taken seriously.

So that brings up the question as I am what you could consider 'on the fence' about this topic. Is a person 'delusional' if they identify as an animal or even a machine such as a jet airplane or a helicopter?
