A lot of people who thought Julian Assange was a hero have now immediately contorted themselves in some elaborate rationalisation. Others who thought he was a dangerous anarchist are feeling a strange new respect for him, equally automatically. Even those who always regarded him as an ambiguous figure will find their internal evaluation of him affected. That last includes me, who regarded him as odious but probably necessary in the world, and now find him to be a dangerous fellow, but stand-up guy.
Here's the interesting part: We all change our opinion of Assange, not the people he exposes. The Clinton supporters will be unaffected. As the US military supporters were unaffected by his earlier revelations.
Except perhaps a bit. None of us changes his mind all at once, but stories like these can contribute to rather thorough changes.
