It was never really clear what the so-called porn filter was supposed to achieve; what problem it was trying to prevent. Filtering seems to have become a crutch for inept parents looking for an easy way to avoid having real conversations with their kids about sex, porn and the world outside their comfortable little cul-de-sacs. If their first sight of a vagina traumatizes your teenage child, then you have brought them up wrong – but of course the problem here is often the parent more than the child; the embarrassed mother of father – projecting their own feelings of discomfort and embarrassment around the topic of sex onto their child. There remains, despite a wave of public hysteria, no good evidence that porn has any detrimental effect on children.

What clearly does have an impact on children though is denying them sex education, suppressing their sexual identity, and shutting off access to child protection or mental health charities. In all this talk of porn filters, the rights of the children campaigners supposedly want to protect have been ignored or trampled. Children should have a right to good quality sex education, access to support hotlines and websites, and information about their sexuality.
