Top definition
The act of believing in the objective medical reality that there are only two genders, as defined by chromosomes XX (female) and XY (male).

The word is often used to degrade and invalidate the opinions of those whose beliefs are contrary to mainstream feminists and LGTBQ activists arguing that there are more than two genders.

The act of cissexism is likely to become classified as hate speech in Canada.
Parent: "Doctor, last night my teenage child started bleeding from their genitals".
Doctor: "Don't worry, it's probably normal. What is the gender of the child?"
Parent: "My child is non-binary genderqueer."
Doctor: "Yes but... are they male or female?"
Parent: "That is cissexist."
