Nobody had ever been extradited for this sort of thing. Sweden is special in that it enabled it based on a testimony, even after the testimony has been revoked and without the victims pressing charges or even agreeing with the interpretation of the police.
This is not an example of the legal system taking too much liberty of the notion of rape. This is much more likely an example of state level conspiracy.
Men are not under threat, sharing potentially incriminating information about the USA just means that nobody is playing by any rules.
Don't embarrass yourself or others to have this debate about rape. As an academic exercise, sure go ahead, but this case does not prove that rape laws in Sweden are used unfairly. It just proves Sweden, like most smaller Western nation's have little choice but do what the big man in Washington whispers in their ears.
This also does not prove Assange is guilt free. But at least if we want to maintain any illusion that we live in a free world: he is a deserved a court case about the actual actions that are fuelling this hunt.
So please just don't use the word rape and Assange in the same sentence. It's a disservice to actual victims, whistle blowers and our cultural identity as such.
