"Anyone who hasn't noticed the violent misogyny of many so-called trans rights activists hasn't been paying attention. Women like me, JK Rowling, Rosie Duffield and others who have been on the receiving end of rape and death threats know this all too well. Signs such as those we saw on Saturday threatening murderous violence against any other group would cause outrage, but they are commonplace at such demonstrations. I'd like to see the leaders of the parties of all parliamentarians present on Saturday squarely condemn what occurred."
