Maybe he never intended harming any women or girls, but it's interesting that he targeted a girls' school and made reference to 'terfs', which is quite a specialist term.
But my point remains: the hyperbole about literal genocide, the Days of Remembrance etc etc gives the false impression that transpeople in this country are oppressed, marginalised, under constant threat of annihilation and that can result in violent action being taken in 'self defence', or revenge - it has happened in the US -'keep bashing us but do not wonder why we Go BERSERK' as Robert Dugan wrote before he shot five people dead.
If Darren Rigby was just a hoaxer who happened to randomly pick on schoolgirls and terfs to threaten with death, that's good. Unfortunately, in some cases, it's not a hoax.
