The screening of a controversial film about transgender issues has been canceled for a second time by the University of Edinburgh after student protests. Gender-critical documentary Adult Human Female was due to be shown at a lecture hall in George Square on Wednesday. But the university said protestors were restricting access to the venue and the event was canceled on safety grounds. A similar protest in December stopped the first attempt to screen the film. Some university staff and student groups had called for the screening to be called off, claiming the documentary contained content that was a clear attack on trans people's identities. A statement from the film directors said "There isn't an iota of hatred in our film. The accusation that the film is transphobic is designed to shut down debate. #queer_up_education
