>>3586700>down syndrome does not effect the arrangement of sexual organs so is irrelevantIt is relevant in the sense that it is a parallel to it, they are the same type of problem, just with different effects
>a person with both male and female sexual organs constitutes a third gender and is the only real gender outside of the standard male femaleNo, it is a defect since having a redundant sex chromosome is neither normal nor consistent. Hermaphrodites do not always have the same selection of shared sexual organs, let alone completely functional ones.
>since female is the default setting for all developing fetus then you just described being male as a genetic disease, dumbassObjectively incorrect, X chromosome is not the "default gender-determining" sex chromosome, Y is, and they are both completely separate. Yet, we evolved with both since our change from apes to humans, as does other non-asexual animals.
