I started to not understand what I was reading when I reached the word “Sociologists”...
Sociologists Kristen Schilt and Laurel Westbrook define cisgender as a label for "individuals who have a match between the gender they were assigned at birth, their bodies, and their personal identity".[1] A number of derivatives of the terms cisgender and cissexual include cis male for "male assigned male at birth", cis female for "female assigned female at birth", analogously cis man and cis woman,[5] and cissexism and cissexual assumption.[6] In addition, one study published in the Journal of the International AIDS Society used the term cisnormativity, akin to sexual diversity studies' heteronormativity.[7][8] A related adjective is gender-normative because, as Eli R. Green writes, "'cisgendered' is used [instead of the more popular 'gender normative'] to refer to people who do not identify with a gender diverse experience, without enforcing existence of a normative gender expression".[9] In this way, cisgender is preferable because, unlike the term gender-normative, it does not imply that transgender identities are abnormal.
Now do you understand?
