They couldn't show the film though could they? The 'push back' involved masked thugs bodily stopping women from entering a legal event for which they had tickets and the security staff didn't do their jobs to protect those women. As much as you and footstampers dislike it, gender critical views are "worthy of respect in a democratic society" (in fact a protected characteristic no less) and part of being a democratic society is the existence of plurality of views.
And no, it's not just about 'bathrooms'. It's about rape crisis services, domestic violence shelters, prisons, crime statistics etc etc etc.
But you know that. You just don't care.
