Gender essentialist

Gender essentialism&mdash;also called biological essentialism or bioessentialism&mdash; is a belief that treats gender and sex as interchangeable terms, claiming that all people are essentially male or female. Gender essentialists regard gender as a binary pair that are complete opposites with separate traits that can all be attributed to their biology. Essentialists sometimes (misleadingly) claims to support transgender people by saying trans men and trans women have a body of one sex with "a brain of the opposite gender"; however, they usually deny trans people's genders by weaponizing biology: reducing people to chromosomes and genitalia under the assumption that there are no variations in sex traits. This concept completely erases the existence of intersex people and various non-binary genders.
