Earlier quoted context omitted.
It could always be both. Assange is probably persona non grata to the British authorities, but even if you wanted to manufacture some cause to imprison him, you wouldn't go for fabricating a rape charge in Sweden. At most, the British authorities are reacting opportunistically to an otherwise valid, legitimate charge.
I agree 100%. I wonder if those defending Assange would do so if he were accused of raping someone they care about.
And if you read up on the details of the story, and the context, it's very fishy. It's at best a case of he-said vs she-said --- arguably one of the perfect ways to smear someone's reputation and cause them legal and financial hassle, without having to meet the minimum legal standards to convict someone of guilt beyond all reasonable doubt. Men and women have sex ALL the time, 24/7, all across the world, in all sorts of complex ways, variations, situations, and very often without condoms. It's also a fact that a large percentage of women like men to be dominant with them and it arouses them.
Given all these facts, and this cultural context, it's hard to know exactly what happened behind closed doors in these incidents, and before the legal system ruins a man's life they need to be damn sure they're doing the right thing. From just what's known publicly so far this case looks so flaky and muddled and suspicious that a reasonable person could easily say those standards aren't met here.
