But to apply the same criticism to Edward Snowden is a whole different thing altogether. He has produced reams of evidence on the practices of the US intelligence agencies, for him to be "fundamentally dishonest" would involve fabricating large chunks of that, and if I believed that then I wouldn't stop at "dishonest" I'd go with "crazy" or worse.

Edit: And just to add in this particular case I'm in agreement with you, his arguments do seem compelling.
Greenwald's condemnation of The Guardian's summary of Assange's interview seems accurate. But Greenwald's assessment of Harris, and his tweets in that matter, seem very biased.
Each of these people should be looked at based on their own actions.
