>rape and child porn/molestation. Once someone has been accused of those, people seem to lose all objectivity.
The converse is true also. Those that support Wikileaks appear to believe that it is impossible for Mr Assange to have committed any crime and that the grievous nature of the accusations means that it's all a conspiracy.
If the accused were guilty the best thing to do would be to make a big leak (I gather they hold information and don't leak it immediately, a power play for sure) immediately before the accusations became widespread or before being arrested at the latest - that way the support of those without objectivity on your own side can be won.
In short, lack of objectivity is a two way street.
