I took "Don't pick through it, see what you think will make headlines or embarrass people you don't like, and publish only that which you feel is fit to press." to mean that everything should be printed. Otherwise he needs to decide what he feels is fit to press, and what is fit to be redacted.
Now you are saying that he should redact certain items. What judgement should he use for that? Since it seemed like you were questioning his ability to make that judgement.
I think Greenwald's slow release of the files from Snowden has done a superb job of making the US wary about what it can do and say, which I think was part of Greenwald's agenda. Compare that to the Wikileaks cable release which, once it went public, had a burst of fingerprint pointing and then became yesterday's news.
I don't understand your statement. The Newsweek describes Assange as beliving "the liberating power of the Internet is based on its freedom and statelessness". How is liberation not part of a humanitarian goal? Based on what he's said, his political agenda is meant to pursue his humanitarian agenda.
So even if I'm wrong, and there are people who have no political agenda, why do you say that Assange has a "political agenda", when it's apparently actually his humanitarian agenda that you see?
