Men who eat meat should be banned from having sex, the animal rights organisation People for the Ethical Treatment of Animals (PETA) has declared.

Terry Crews has been widely criticised for saying the children of same-sex or single parents will grow up "severely malnourished".

The Brooklyn Nine-Nine star has become a celebrated figure for advocating for women and for his 2017 testimony about allegedly being assaulted by another man.

But public opinion might be shifting against Crews after he made a series of tweets about parenting.

It began on February 25, with him complaining about a New York Times article that accused President Barack Obama of "scolding" young black men.

Crews said he was bothered that a female journalist had written an opinion piece "about how boys should be taught to grow into successful young men".

"How would she know?" he asked.

If a successful black man can’t advise the black male youth of the next generation, who will?

THE STREET. That’s who.

Another thing that bothers me is that this OP-ED was written by a WOMAN about how how boys should be taught to grow into successful young men.

How would she know?

MEN NEED TO HOLD OTHER MEN ACCOUNTABLE.

That tweet provoked accusations of misogyny, which Crews denied - and then it all got much worse.

"I've reiterated many times that same sex couples and single parents can successfully raise a child," he wrote on Saturday (local time).

"But I believe paternal AND maternal love are like vitamins and minerals to humanity. No matter where you get that paternal and maternal love. MY purpose is to give paternal love."

Another Twitter user replied: "Love is not gendered. A child will not starve with only one gender loving them."

"But they will be severely malnourished," was Crews' response.

A retreat offering meditation, yoga and reflection has attracted headlines all over the world for banning white people and men from attending.

The Women of Color Healing Retreat, held in the southeast Costa Rican city of Puerto Viejo, is designed as a sanctuary from the "racist ideology" of the US, and to connect African-Americans "to nature and themselves".

Founder Satya X says the retreat's goal is to have a week of healing and community building, which involves "enriching women-centred" workshops, hiking, swimming, meditating and self-care practices.

But the retreat founder's denial of Caucasian and male attendees has garnered the most attention, following a recent video report by Vice News.

In the footage, retreat runner Andrea X says she feels as though white people are "everywhere".

"I feel white people shouldn't even have passports," she said. "I have no tips for white people, let us have our space.

"Let us have our room and [you] hang out with other white people - you've done enough damage."

Andrea X says the ultimate goal of the retreat is to create a "community of black people" living in the central American nation.

She denied that idea could be viewed as motivated by the same hatred as white people who want segregation from blacks.

"It has nothing to do with [anyone else]. This is about us healing our community."

In another part of the video, retreat-goers said they would struggle to be as open and honest if, white people had been allowed to attend.

For many, the presidency of Donald Trump had pushed them to travel to go on the retreat.
