Omnisexual (often shortened to omni) is a redundant sexuality that is literally the same thing as bisexuality.
Omnisexuality vs. Pansexuality
Pansexuality and omnisexuality are very similar as they both involve insufferable biphobic and transphobic people who think they're special for "allowing" trans people into their attraction.
History
The word omnisexuality appears as early at the 1959 beat poet Lawrence Lipton's The Holy Barbarians,[1] but the first time it was described in the context of the current definition was in a 1984 text titled simply Sexual Choices: An Introduction to Human Sexuality.[2]This text described omnisexuality as "a state of attraction to all sexes", stating that some researchers believe that every individual is born omnisexual before developing their sexual attraction into the labels of homosexual, heterosexual, or other orientations.
The term spread even further in the early 1990s as M. Jimmie Killingsworth undertook an analysis of the poet Walt Whitman.[3] In Killingsworth's study, he found that Whitman had a general omnisexual character throughout his work The Leaves of Grass. In the 2010s, The Atlantic noted that his poetry expresses sexuality towards all genders, sometimes even the sea or the Earth.
Omnisexual was a common message board term in the 2000s. The knowledge of this term was boosted even further when several celebrities, such as Janelle Monáe and Brendon Urie, came out as pansexual. The media made several non-monosexual terms known in the mainstream as that took place. Many popular articles discussed omnisexuality alongside these celebrities' pansexuality.
Some fictional characters, such as Jack Harkness from Doctor Who, the Marvel character Deadpool, and Kevin Crawford from Paradise P.D. have has been canonically confirmed as omnisexual.
Etymology
The prefix omni- comes from the Latin word omnis, meaning "all". Pan-, which the term pansexual comes from, also means "all", and is of Ancient Greek origin.
