I've been listening to people argue that Assange is not a journalist because he presents information and does not spin it. The same people will then acknowledge that he has written editorials and commentary. They'll say he's a pubisher, not a journalist.
It's all quibbling. Journalists present information about the world. Some try blatantly to interpret it, some try subtly. Some interpret it with their choices of information. It's all journalism--it's all the news that the journaler thinks is fit to print. Assange deserves every consideration that any journalist deserves.
