People shouldn't endorse causes that they don't understand, but what is the bar you're setting for understanding? Do I have to have read the court records to support Peltier? Maybe one of those "unbiased" national newspaper articles you mention (unbiased media? Don't make me laugh!). The New York Times is no less biased than some crudely mimeographed left-wing propaganda pamphlet, they're just more subtle about it. See Noam Chomsky. And sometimes, in the absence of mainstream coverage of an issue, propaganda is one's only source of information. The more times people say Peltier's name, the less he is forgotten, the greater the chance he will get out of jail before he is an old man. It is not a "bandwagon", it's justice (ie. a fair trial, with untainted evidence!), and a man's life. If you don't understand that concept, stop making smug declarations about a movement's "authenticity". The activists are just trying to make sure you (or you, or maybe you over there!) are not the next Leonard Peltier. Remember, in an unjust system, nobody is safe.
