Starting late last year, Internet service providers in Britain made “family-friendly filters,” which block X-rated websites, the default for customers. Now any account holder who wants to view adult material needs to actively opt in — effectively raising a hand to say, “Bring on the naughty.”The initiative, which was conceived and very publicly promoted by the government, is intended to prevent what Prime Minister David Cameron called the corrosion of childhood, which, he argued in a speech last year, happens when kids are exposed to pornography at a young age. In the same speech, he seemed to toss teenagers into the group in need of protection, referring to “young people who think it’s normal to send pornographic material as a prelude to dating.”
