Saying no to dating is part of a growing ultraconservative social movement in Indonesia being spread through Instagram and WhatsApp. “When I look at couples, I see my old self, how I used to be affectionate in public, holding hands, hugging,” says 23-year-old Yati, “and now I think that’s disgusting.” When Yati broke up with her ex, she didn’t just swear off dating; she joined Indonesia’s anti-dating movement - Indonesia Without Dating. Its leaders say dating is expensive, gets in the way of study, and - most importantly - is against religious teaching. For Assignment, Simon Maybin discovers it is part of a wider youth-led surge in conservative Islam in the world’s most populous Muslim-majority country. Opponents see the phenomenon as a backwards step for women and a threat to Indonesia’s religious pluralism.
