Definition of "cisgender"

To uphold the inequality that we choose to engage in, we regularly present the myth that trans people are deviant or a danger to cisgender people.

As trans people, we have many cisgender allies—those who show their support for the concerns, needs, and rights of trans people, even though they may not personally face the same issues.

R. Moskowitz charges cisgender readers to be as conscious and deliberate with our religious identities as transgender and gender non-conforming people are with theirs, arguing that holiness is only achieved through continuous and unrelenting struggle and change.

Gender assumed many roles in this pandemic. Cisgender men were more likely to die from the virus, which seemed to be about inherent vulnerabilities of those with XY chromosomes.

Transgender people report discomfort with their birth sex and a strong identification with the opposite sex. The current study was designed to shed further light on the question of whether the brains of transgender people resemble their birth sex or their gender identity. For this purpose, we analyzed a sample of 24 cisgender men, 24 cisgender women, and 24 transgender women before gender-affirming hormone therapy. We employed a recently developed multivariate classifier that yields a continuous probabilistic (rather than a binary) estimate for brains to be male or female. The brains of transgender women ranged between cisgender men and cisgender women (albeit still closer to cisgender men), and the differences to both cisgender men and to cisgender women were significant (p = 0.016 and p < 0.001, respectively). These findings add support to the notion that the underlying brain anatomy in transgender people is shifted away from their biological sex towards their gender identity.

Even in regard to cisgenders, research shows that it's “easier” for people to identify male than female features, meaning that the default “visible” person in our culture is male “unless proven otherwise.”
