Isogender

 is a Gender Modality that refers to when one is not Cis, but also does not identify as Trans either.

Some examples of people who may identify as Isogender include:
 * A Bigender, or otherwise Multigender person who 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.
 * An Agender, or otherwise Genderless person who does not feel like trans describes them due to their lack of gender.

Etymology

 * iso comes from the word isomer, as Cis and Trans are isomer types.

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?""
