The NSPCC has become embroiled in a row with Mumsnet users after defending the right of transgender girls to join the Girl Guides. The children’s charity called off a planned live event about keeping children safe from abuse on Friday after users repeatedly asked questions about allowing transgender children into single-sex spaces. Users raised concerns about children who identify as female, but who were born male, sharing changing rooms, shower facilities and dormitories with other Girl Guides. Other participants asked about the increasing number of children who are deciding to live as a different gender while still at school. A staff member posted to say the event had been cancelled “because the questions here are so focused on gender identity, the feeling is that the NSPCC campaign itself and the NSPCC’s specific safety messages are unlikely to get much of an airing.” In a statement to the site the NSPCC said it “doesn’t consider there to be specific child protection concerns in relation to trans-inclusive policies.” The spokesman added: “Trans young people are at particular risk of physical, sexual and emotional abuse from peers.”This can heighten the risk of abuse by adults as children turn online for support and access to networks of those sharing similar views and feelings. Mumsnet users have built up a reputation for being particularly focused on transgender issues, and the stance of some members has been described as “transphobic”. Justine Roberts, Mumsnet founder and CEO, told the Daily Telegraph that the site “will always have a great deal of sympathy for vulnerable and oppressed groups but we are also committed to freedom of speech.”Sometimes these two principles come into conflict, rarely more so than in the recent debate about what it is acceptable to say, or not to say, about trans people, and changing opinions about gender and sex.”She added that the debate over transgender people’s rights had tested “to the absolute limit” the site’s ability to host “civilised discussion”. “But we fundamentally believe that with a bit of an effort all round then we can allow all voices to be heard and that by allowing all sides to be heard we can move towards a constructive compromise,” she said.
