When Tara Wolf assaulted Maria MacLachlan at Speakers’ Corner on September 13th 2017, a social-media dispute between transgender activists and radical feminists burst out onto the streets of London. Ms MacLachlan, a 60-year-old woman, was going to a feminist meeting that had been forced to move to a secret venue after protests by a group of transgender activists that included Ms Wolf, a 26-year-old trans woman.
