The estimable Jack of Kent (aka barrister David Allen Green) provides the public service of enumerating the European Arrest Warrant allegations against Julian Assange. So whatever your opinion of him, now you can argue for his arrest / freedom / hanging / public adulation based on the alleged facts.
From item 2 ("Sexual molestation") of the EAW complaint:
On 13-14 August 2010, in the home of the injured party [AA] in Stockholm, Assange deliberately molested the injured party by acting in a manner designed to violate her sexual integrity. Assange, who was aware that it was the expressed wish of the injured party and a prerequisite of sexual intercourse that a condom be used, consummated unprotected sexual intercourse with her without her knowledge.Assuming that the veracity or otherwise of party AA's allegations is unknown, one has to wonder at anyone who claims that Sweden's attempted extradition of Assange is a plot to hand him over to the Yanks. If AA and Assange were both resident in Britain, I doubt we'd see many people rushing to defend Assange's actions as the inevitable High Court case approached.
If you want to argue based on established facts, you'll have to wait for a court case. Don't hold your breath...
