User blog comment:Gundam Legilis/The Fallacy of The White Fang/@comment-10380701-20140422001553

Out from my butt, but I'd say that the members of White Fang are those that were greatly involved in the Faunus Rights Revolutions. Maybe descendants or family members depending on how far into the timeline that happened. Initially starting with protests, more violent actions start popping up once a more militant-esque leader stepped in.

That's how I put it anyways.
