Supporters of a website led by a man who says rape should be legalised on private property are set to meet up in cities around Australia, sparking a backlash on social media.

'Tribal meetings' planned for February 6 in several Australian cities Women take to social media to express outrage

According to the Return of Kings (ROK) website, the US-based group believes "a woman's value significantly depends on her fertility and beauty", and the elimination of traditional sex roles "unleashes women's promiscuity".

The site is designed to be a "safe space for heterosexual men" who believe "men should be masculine and women should be feminine".

"ROK aims to usher the return of the masculine man in a world where masculinity is being increasingly punished and shamed in favour of creating an androgynous and politically-correct society that allows women to assert superiority and control over men," the website states.

The "tribal meetings" are planned for February 6 in Sydney, Melbourne, Brisbane and Perth. They are being held on that date in 43 countries, according to the site.

Supporters have a 20-minute window to meet their host at a pre-listed destination, like the fountain at Sydney's Hyde Park, before they move to their final undisclosed destination, most likely a bar, the Return of Kings website said.

Since the controversy surfaced earlier on Monday, "neomasculinist" Daryush Valizadeh, the creator of the group, has announced he will come to Australia for the event.

"F*** it, I just booked a flight to Australia. See you somewhere there on 2/6. I'll stay a while, see some sights," Mr Valizadeh, 36, tweeted with an screen shot of flight options to cities in Australia.

Some women have taken to social media to express their outrage at the meet-up and the group's controversial views.

Greens MP Larissa Waters said on Twitter she "thought it was a hoax, their views are so medieval. Any 'meetings' will tank".

Former sex discrimination commissioner Elizabeth Broderick said Return of Kings' views were "deeply offensive and have no place in Australia".

Feminist writer Clementine Ford said: "If Doosh wants to make it legal for men to rape women on private property it's only fair that we make it legal for those women to kill them."

Writer and activist Melinda TankardReist tweeted: "So provocative that they are choosing to meet out in the open. They want us to know they hate us."

Site advises men to 'stop asking for permission'

Mr Valizadeh, 36, published a blog post on his personal website suggesting legalising rape on private property is the solution to the United States' rape culture.

"Without daddy government to protect her, a girl would absolutely not enter a private room with a man she doesn't know or trust unless she is absolutely sure she is ready to sleep with him," the blog post said.

His blog also features sections for "pick-up tips", advising men to "stop asking for permission", and a link to his "Bang Guides: strategy guides for getting laid at home and abroad".

A Frequently Asked Questions page for the event says transsexuals, homosexuals and women are not welcome, and outlines what to do if "a pretty girl shows up" — the answer being "get her number and tell her to buzz off".
