What Is A Woman

The film features Matt Walsh asking "What is a woman?" and related questions to a variety of people. The film discusses sex reassignment surgery, puberty blockers, transgender youth, and transgender athletes in women's sports.

Those interviewed include politicians, a pediatrician, a gender studies professor, a psychiatrist, a gender-affirming family and marriage therapist, a transgender opponent of medical transition for minors, a surgeon who specializes in gender-affirming surgery, a father of a 14-year-old transgender boy, and media personality, psychologist, and author Jordan Peterson. Walsh also discusses the terms "non-binary" and "transgender" with a Maasai tribe in Kenya and talks to a gay man practicing public nudity in San Francisco.

The film features a speech given by Walsh at a meeting of the Loudoun County School Board in Virginia (he is from Tennessee) that was called so people could express their opinions on Policy 8040, which instructs staff members to use the preferred name and pronouns of transgender students and allows the students to use school bathrooms and locker rooms that align with their gender identity. During the speech, Walsh says: "You are all child abusers. You prey upon impressionable children and indoctrinate them into your insane ideological cult, a cult which holds many fanatical views but none so deranged as the idea that boys are girls and girls are boys."
