"It's just weird to talk about your sexual feelings to your parents," says 15-year-old Ben*.

His parents, Sophie and Martin, two professionals in their 40s, nod understandingly. They are discussing the kinds of "big issues" Ben's social media usage throws up, and for Ben their conversations about sex and pornography are "the worst".

But the qualities that make him popular with his peers often land him in trouble with his teachers, who give him detentions or send him to isolation for making what his mother describes as "inappropriate comments".

In the show, Jamie and his peers use language associated with the "manosphere" – websites and online forums promoting misogyny and opposition to feminism – and incel culture. Incels, short for involuntary celibate, are men who blame women because they are unable to find a sexual partner. It is an ideology that has been........
