A person who is born with a penis likely is XY, probably has "male" described hormones, etc. etc. No one is debating that. There are no lies. We are debating definitions here. "Male" describes masculinity. You are assuming that certain male qualities outweigh others in that defining process. Biological facts are rigid, but the way we describe them and interpret them are not, inherently.
For example, the physical structure in the brain that determines gender - that could be male. It is also by definition not delusional - because it is accurately describing itself. So why isn't that person male if they have other female described traits? Your philosophy that determines what is most important is what does. And of course this is just a fun concept for you to debate against without having to deal with actual excruciating consequences - like those this debate actually affects.
