Consistent with common usage of the term “cisgender,” the graphic below explains that “…if you identify with the gender you were assigened [sic] at birth, you are cis.”
Another Trans 101: Cisgender webpage describes cis this way: “For example, if a doctor said “it’s a boy!” when you were born, and you identify as a man, then you could be described as cisgender.” [i] Likewise, girl-born people who identify as women are also considered cisgender. WBW are cis.
Framing gender as a medically determined assignment may seem like a good start to explaining gendered oppression because it purports to make a distinction between physical sex and gender. Feminism similarly understands masculinity and femininity (e.g., gender) as strictly enforced social constructs neither of which are the “normal” or inevitable result of one’s reproductive sex organs. Feminism and trans theory agree that coercive gender assignments are a significant source of oppression.
