Parents should remain free to speak openly about transsexualism online, Cabinet minister Liz Truss says. The Chief Secretary to the Treasury backed the head of Mumsnet – Justine Roberts – for defending free speech on the parents’ platform at a time of intense debate. Truss’ comments were praised by some, but one leading transsexual activist attacked her stance, suggesting she “could be investigated”. Earlier this month Roberts said the “thought-police” were closing down debate on the issue and rushing to malign people who disagree. She said “a section of the hardline trans side” thinks “any discussion at all is by definition transphobic”.
