RODNEY HIDE: MPs Who Can’t Tell Boys from Girls

What a revealing night we had last week in Parliament.

The Legislation (Definitions of Woman and Man) Amendment Bill had its first reading — a modest, common-sense attempt to insert basic biological reality into law: a woman is an adult human biological female, a man is an adult human biological male.

Yet the opposition’s response was pure ideological theatre.

Labour’s Vanushi Walters called it “irresponsible” and a “platform for hate.” Chlöe Swarbrick declared, “What is a woman? Whatever the hell she wants to be.” Glen Bennett spoke emotionally about his identity while implying the bill marginalises trans people. Oriini Kaipara invoked Māori philosophy to suggest the bill discriminates.

One is left genuinely confused. These are elected lawmakers — supposedly intelligent adults — standing in the House arguing against a truth that toddlers master by age two.

Here is the biology they seem unable to grasp.

Sex is determined at the moment of conception. The chromosomal combination (XX or XY) is fixed the instant the sperm meets the egg. That genetic reality exists in every single cell of the body — trillions of them — except the gametes. From the earliest embryonic stage, males and females follow different developmental pathways. This is not assigned at birth. It is immutable biological fact.

By 18–24 months, normal children can reliably distinguish male from female. By age three, most can correctly identify themselves and others as boy or girl. This is hardwired human cognition.

Yet here we have MPs who apparently cannot make the same distinction. They treat biological sex as optional, fluid, or “whatever the hell she wants to be.” They lecture the rest of us about “hate” for simply wanting laws grounded in observable reality.

Jenny Marcroft was right: women fought for sex-based rights for over a century. Those rights — safety, fairness in sport, privacy in single-sex spaces — are now under sustained attack.

For the men, remember: the MPs who voted against this bill want men who simply say they are women entering your mother’s, wife’s, girlfriend’s, or daughter’s changing rooms and toilets. For the women, remember: the MPs voting against this bill don’t want you safe.

This is not compassion. It is ideological capture. It is adults sacrificing women’s safety, fairness, and dignity on the altar of the latest progressive delusion. Protecting sex-based rights does not deny anyone’s right to live free from harassment. It simply refuses to erase the meaning of “woman” and “man” from our laws.

The bill has gone to select committee. Good. Let New Zealanders speak. But the first reading exposed something alarming: a chunk of our political class has less grasp of biological reality than the average three-year-old.

That is not a good look for the people we pay to make our laws. Parliament should pass this bill and restore clarity, sanity, and basic decency to the statute book.
