No dating, sex, marriage or having children with men: South Korea’s extreme “4B” feminist movement has gone viral in the United States and beyond since Donald Trump won the US presidential election.

In Korean, 4B means the “Four Nos”: dating, sex, marriage, and having children with men.

The movement emerged in the mid-2010s in South Korea, against a backdrop of persistent wage disparity, entrenched gender roles, and an epidemic of cybersexual crimes and sexual violence against women.

However, it has largely remained a fringe campaign.

Supporters like Baek Ga-eul, 33, say it has allowed them to be a “complete human being, not just a being reserved for a man or a boy.”

The movement arose because South Korean women – who do 3.5 times more work at home per week than men, official data shows – cannot “accept the expectation of doing as much paid work as most household chores,” said.
