People for the Ethical Treatment of Clois (PETC), with more than a million members and supporters*, is the largest fandom rights organization in the world. Founded in 2006, PETC is dedicated to protecting the Clois characterization from the Smallville writers who seek to butcher it. PETC operates under the simple principle that everything is Lana Lang's fault.
