"Placing faith in a sociopath is a sign of a weak mind."
I think that's the one. Unless you have evidence that Assange is a sociopath of course.
Assange and his followers have IMHO been a bit childish at times and they are certainly playing the PR to the max, but unfortunately the world needs Wikileaks, cryptome etc. When one has government hires securing the services of "dancing boys" and covering it up, one has a serious problem. A mature person would, of course, censure the culprits like any other padeo; but instead our masters see no real issue with it and cover it up.
It takes something like Wikileaks to get the truth out.
Then there is undue pressure applied to democracies to implement draconian laws (e.g. USA making outrageous demands on Spain). Once again we (the public) need something like Wikileaks to get the truth out.
Assange may or may not have issues, but that does not detract from the good which has come from Wikileaks.
