Trinary Genders

Ternary or trinary genders are three primary pre-existing gender identities accessible within ones own culture. This gender arity includes binary genders and a tertiary gender. This tertiary identity can be a third gender or other abinary identity, such as neutrois/neither (or none), or liaspec intercidogender, such as androgyne/both, generally monogender, not necessarily allogender.

Gender trinarism is often considered a form of exorsexist discrimination towards non-trinary and atrinary individuals, reinforcing an extension of gender binarism. It could be either in ways of language or identity.

History
The first mention of gender trinary is recorded since March 2018. It was sometimes used interchangeably with gender quaternary as both and neither can be two tertiary identities.

In June 2018, Tumblr user exorsexistbullshit defines gender trinarism as the idea that all non-binary people are just a separate gender from women and men. The term is later used in some academic articles.
