Feminists, liberals, and social justice warriors suffered a massive blow in Australia on Wednesday when the country's most populous state banned high school teachers from teaching the concept that gender is a social construct.

The Australian reported that an independent review into the New South Wales' sex and health education resources found that the state schools were pushing gender theory in 11th and 12th grades.

Teachers will now be forbidden to teach that gender is "social construct," sexuality is "non-binary," and/or it's "constantly changing." Furthermore, a plan to "de-gender" school language has been scrapped. Teaching aids like the "Genderbread Person," which tells students there are an infinite amount of different genders available, will no longer be used.

A review of teaching resources was also implemented. Teachers were told to abandon a 17-page long list of "teacher's toolbox resources" given in Crossroads, the state’s compulsory sex education program.

Included in the list of newly banned resources was a lesson plan called "Opposite Ends of the Pole." It encouraged 10th graders to "consider various case studies, including 'Joseph', a man married with three children who 'masturbates [and] fantasises only about men' as well as 'Alex', who had sex with girls as a teenager but has developed a relationship with a man since moving to a country town."

Parents will have access to the full report so they can see exactly what goes on in their child's education.

Parental involvement, what a noble idea.
