Isogender

Isogender  is a gender modality that refers to when one is not cisgender, but also does not identify as transgender either. Examples of people who may identify as isogender include:
 * 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.

Etymology
The term "iso" comes from the word isomer, as cis and trans are isomer types.

History
Isogender was coined by an anonymous ask to the Tumblr user Bigendering on June 9, 2017.

Flags
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).

Coining
''Anonymous asked: This isn't a question, just me being a nerd, but since I'm bigender (woman and nonbinary) and I'm AFAB, I don't really feel trans because my gender isn't GOING anywhere, at least, that's how I feel, but I'd prefer they/them so I'm not cis exactly, so I now use "iso" to describe myself because it comes from isomer and cis and trans are isomer types. aaaanyway, I hope you're having a good day''

"Ooh I love it! (Biology nerd here)

Would iso be a good term for anyone who doesn’t feel either cis or trans, or for anyone who doesn’t feel cis?"
