Australia's government has scrapped two sex education videos designed to teach teenagers about consent and sexual assault after they were widely panned.
The online education campaign used metaphors such as smearing milkshake on someone's face in order to depict disrespect and abuse.
Equality activists described the videos as "bizarre" and "concerning".
Officials removed the milkshake video and another on coercion in which a girl wonders whether to swim with sharks.
A Department of Education, Skills and Employment spokesperson cited "community and stakeholder feedback" for taking the two videos down, the ABC reported.
The federal government had originally defended the campaign, which it said was created with the help of experts.
The decision to pull the videos followed criticism from senior figures in both the governing Liberal and opposition Labor parties, as well as numerous activists and campaigners.
New South Wales Education Minister Sarah Mitchell, a Liberal politician, called the videos "woeful" and a "missed opportunity".
"I think we should be much more up front with young people when we talk about these issues."
The online learning platform, published on The Good Society website, includes more than 350 videos, stories and podcasts. It was developed as part of the Australian government's Respect Matters programme, to teach respectful relationships in schools.
One video, designed for students aged between 14 and 17, shows a teenage girl smearing milkshake on her boyfriend's face without his permission. The video then uses other examples of eating pizza and "touching your butt" as situations where permission would be required.
Another video about respecting other people's decisions and choices shows a teenage girl doubting whether she wants to swim with sharks, while a boy tries to convince her to do so.
A section entitled "sex and gender norms" confuses "norms" and "myths", for example, by suggesting that ideas such as "males enjoy sex more than females" and "females that wear short skirts want sex" are examples of gender norms.
The Good Society's website describes the learning material as an "engaging, flexible, online program that helps students develop safe, healthy and respectful relationships".
But women's rights activists and anti-rape campaigners say the content is harmful, avoids using the words sex, rape or assault and does not reflect realistic situations or relationships.
Like, teenagers are aware of what sex is? You can just say sex. Surely you would think that when trying to stop people from committing rape and sexual assault, we could just use the words.— Matilda Boseley (@MatildaBoseley) April 19, 2021
Gender equality organisation Fair Agenda has launched a petition calling on the Australian government to work with violence prevention experts to replace the "concerning and bizarre" content.
"Young people deserve consent and respectful relationships training that practically and explicitly helps them understand how to ethically navigate relationships," it said.
Fair Agenda also said the website failed to meet Australia's national standards for the prevention of sexual assault through education. It uses the website's "further information" page as an example, which tells students they can report "any sexual violation" to the Australian Human Rights Commission, but does not recommend telling a trusted adult or the police.
Sharna Bremner, the director of the Australian organisation End Rape on Campus, tweeted: "There is some good information on the site. But there's also some really harmful stuff, which outweighs any of the good."
Australian of the Year and sexual assault survivor Grace Tame said the videos were insulting the intelligence of adults and children alike.
"It minimises the experience of rape trauma, it fails to really address the nuances of this complex issue of consent," she told The Drum programme on ABC TV.
The material has also been criticised for being out of touch with modern teenagers, by using references to the Hollywood movie Titanic, which was released 24 years ago, and The X-Files TV series, which finished its final season nearly 20 years ago.
what if we asked boys to think about consent without using object metaphors and instead to think about girls and women as people? not milkshakes, not cups of tea, not unlocked cars, just like, people— Josephine Tovey (@Jo_Tovey) April 19, 2021
In a statement on 14 April, Australia's education department said the programme had been developed in "conjunction with Our Watch, the eSafety Commissioner and the Foundation for Young Australians (FYA), as well as parent, community and principals' groups".
However, Our Watch and the FYA have said that they were barely consulted. FYA told SBS News it had introduced the government to a young person in its network who may have taken part in a confidential reference group in late 2017.
Our Watch, which works to prevent violence against women and children, said in a statement that it "was consulted between late 2017 and early 2019 when the materials were being developed and provided advice. We have not been asked to use or endorse the materials subsequently".
