Lots of people are trying to point out that Assange isn't being accused of rape, but some sort of "not-using-a-condom" silly rape law that is only the law is whacky Sweden, herp de derp feminists de derp political correctness gone mad.
However in order to be extradited from UK, he had to be accused of a crime that would have been illegal in the UK. I suggest you read the High Court extradition appeal case ( http://www.bailii.org/ew/cases/EWHC/Admin/2011/2849.html ). The courts quite clearly decided that it wasn't some weird 'sweden-only' law, but what he was accused of would be a crime in England & Wales.
In fact, he's 'charged' with 4 things:
• "Unlawful coercion" - Holding down a woman with his body and forcing her to have sex.
• "Sexual molestation" - Having sex with someone without a condom when they said they would only have with a condom (this would be illegal in the UK aswell BTW).
• "Sexual molestation" - "deliberately molested the injured party by acting in a manner designed to violate her sexual integrity i.e. lying next to her and pressing his naked, erect penis to her body."
• "Rape" - Having sex with someone who was asleep.
Before you talk about what's going on, read up on the charges.
