Neither the UK or the US governments are 'nice' - ask the Brits who stayed over in Guantamo
Given the history of both the UK and the US governments, especially the anger expressed so publicly by members of the government and congress, Assange is likely wise to have regard for his security.
It is is interesting to see how the UK beneficiaries of Wikileaks downloads is now turning against Assange. The Guardian, along with the New York Times, have really been scraping the gutter trying to disparage Assange.
It makes one wonder why? Is it because they know he is going for different leak partners and the newspapers respective increased circulation, and profits, will suffer as a consequence?
What the newspapers are printing about Assange personally say more about their 'professionalism', or rather lack of it, than anything else.
Whatever personal foibles Assange adopts still doesn't detract from the fact that he has produced the goods in a way, and in a quantity, that no one has ever achieved or is likely to achieve again.
I have no interest in whether he is a cross dresser, has unusual ways of expressing his happiness, or is particular about his security - but I am interested in his product which stands on it's own.
