Executive Order defines "sex" as biological & immutable, while "gender" is indeed fluid, that is, mere identity.
(a) “Sex” shall refer to an individual’s immutable biological classification as either male or female. “Sex” is not a synonym for and does not include the concept of “gender identity.”
(b) “Women” or “woman” and “girls” or “girl” shall mean adult and juvenile human females, respectively.
(c) “Men” or “man” and “boys” or “boy” shall mean adult and juvenile human males, respectively.
(d) “Female” means a person belonging, at conception, to the sex that produces the large reproductive cell.
(e) “Male” means a person belonging, at conception, to the sex that produces the small reproductive cell.
(f) “Gender ideology” replaces the biological category of sex with an ever-shifting concept of self-assessed gender identity, permitting the false claim that males can identify as and thus become women and vice versa, and requiring all institutions of society to regard this false claim as true. Gender ideology includes the idea that there is a vast spectrum of genders that are disconnected from one’s sex.
(b) Each agency and all Federal employees shall enforce laws governing sex-based rights, protections, opportunities, and accommodations to protect men and women as biologically distinct sexes. Each agency should therefore give the terms “sex”, “male”, “female”, “men”, “women”, “boys” and “girls” the meanings set forth in section 2 of this order when interpreting or applying statutes, regulations, or guidance and in all other official agency business, documents, and communications.
(c) When administering or enforcing sex-based distinctions, every agency and all Federal employees acting in an official capacity on behalf of their agency shall use the term “sex” and not “gender” in all applicable Federal policies and documents.
