I made it up. A better term might be 'scourge of the moment'. Most activists have a "cause celebre", meaning - a cause that defines that group in the public eye. E.g. Elian Gonzalez was a "cause celebre" for many Cuban emigres. An object of a group of protestors' ire is commonly called a scourge. So loggers and ranchers, among many others, are the scourge of environmentalists. Put a scourge together with a cause that defines a group and you get (the somewhat clunky but posessing of a certain flair) 'scourge celebre'.
