What Is a Woman

   2022    Culture
It's the question you're not allowed to ask. The documentary they don't want you to see. Are gender roles just a 'social construct'? Can a woman be 'trapped in a man’s body'? Does being a woman mean anything at all? We used to think being a woman had something to do with biology, but the nation’s top experts keep assuring us that is definitely not the case. So Matt Walsh sat down with the experts and asked them directly. He discovers that no one—not doctors, therapists, psychiatrists, or politicians—can actually define the word 'woman'.
Walsh uncovers the shocking and horrifying roots of radical gender ideology and learns exactly how activists and ideologues are trying to brainwash our kids. He also reveals a strategy to defeat the collective insanity that has taken over our society. Join Matt on his often comical, yet deeply disturbing, journey as he answers the question generations before us never knew they needed to ask: What is a woman?
