Intersex

Intersex people have some aspect of their physical sex that is inconsistent with conventional ideas of male and female sex. This difference is in their primary or secondary sexual characteristics, hormones, or chromosomes.

An intersex person may have any gender identity. They may agree with their assigned gender (cisgender), or they may think of themselves as transgender, or it may be more complicated. They may or may not think of themselves as being part of the LGBTIQAP spectrum.

A person with a non-binary gender is not necessarily intersex, and instead may be dyadic (not intersex).

Intersex was one of the 56 genders made available on Facebook in 2014.

Dyadism

Dyadism is a common kind of sexism, the belief that humans are strictly dyadic, having only two sexes. In action, dyadism is discrimination against intersex people. That discrimination can include erasure, harassment, medical malpractice, lack of marriage rights, religious intolerance, human rights violations, and hate crimes against intersex people. Dyadism is also the basis of other forms of sexism, including binarism, the belief that people have only two genders.

Because of dyadism, doctors think of intersex conditions as an irregularity. As a result, intersex people were given so-called "normalizing" or "corrective" surgeries, often at a very young age, and without their consent.
