- A bigender, or otherwise multigender person doesn't feel trans because a significant portion of their gender is the same as their assigned gender.
- A non-binary person who does not feel trans because their gender or gender presentation is similar to their assigned gender as birth. For example, a feminine aligned non-binary person who is AFAB.
- A genderless person who does not feel like trans describes them due to their lack of gender.
Isogender was coined by an anonymous ask to the Tumblr user Bigendering on June 9, 2017. The term "iso" comes from the word isomer, as cis and trans are isomer types.
The isogender flag was submitted on beyond-mogai-pride-flags at May 20, 2018.
An alternate flag was created and submitted to ask-pride-color-schemes on October 22, 2019 with the color meanings as follows : Blue, purple, and pink represent masc, fem, and those who may be a mix of both. The greyscale gradient represents attachment or intensity of gender, from white (entirely agender) to dark grey (strong attachment).
