The Australian Senate has passed a motion brought forward by One Nation, pushing to ban the use of “distorted” gender-neutral language such as “chestfeeding” in official government materials.

The motion was put forward in the upper house on Tuesday by One Nation Senator Malcolm Roberts.

Roberts’ motion stated that “our fundamental biology and relationships are represented through the following descriptors – mother, father, son, daughter, brother, sister, boy, girl, grandmother, grandfather, aunt, uncle, female, male, man, woman, lady, gentleman, Mr, Mrs, Ms, sir, madam, dad, mum, husband, wife”.

“Broad scale genuine inclusion cannot be achieved through distortions of biological and relational descriptors,” Roberts said. “An individual’s right to choose their descriptors and pronouns for personal use must not dehumanise the human race and undermine gender.”

The motion narrowly passed 33-31.

Roberts’ motion called on the government to “reject the use of distorted language such as gestational/non-gestational parent, chestfeeding, human milk, lactating parent, menstruators, birthing/non-birthing parent.”

The motion also called on the government to ensure gender neutral terms are no longer included in any government material, including legislation, websites, employee documentation and training materials.

In his motion, Roberts referred to a doctor from Queensland who “reports incidences of young children feeling stressed and panicked about whether it is okay to use the words boy and girl,” saying that “pushing gender-neutral language [was] no replacement for appropriate emotional and psychological support for children while growing up”.

The decision comes after the Australian National University issued a Gender-Inclusive Handbook encouraging the use of gender neutral terms. Hospitals in the UK have also formally implemented a gender inclusive language policy for its perinatal services department, which included adopting the terms “birthing parents” and “human milk.”

Greens Senator Janet Rice attempted to comment on the motion but was denied permission, taking her frustration out on Twitter later that afternoon.

“I expect this s**t from One Nation,” she said. “But the Morrison Government just voted to support One Nation’s disgusting, bigoted Senate motion trying to deny the identity of trans and non-binary people.

“So the motion passed. What happened to governing for all Australians? Scumbags!”
