Oh wait it's actually called True Humans. My bad. True Humans is basically a militant anti-superhuman group, they're very violent and hateful. PMDF could be an activist counter-part with possible ties to the more violent True Humans. Ridiculous name it may be but then what ativist group doesn't have a ridiculous name? 

Wait, everyone's been reading the Meta Codex, right? Right? *whimpers*
