You realise that on all of the counts listed in the European Arrest Warrant, dual criminality was asserted and thus no UK judge found grounds to dismiss on the basis of lack of criminality in the offences listed?
See page 15 of the following PDF:
And you should also check out what the offences listed actually are, because your description is quite a way off.
The offence described as rape is as follows:
On 17 August 2010, in the home of the injured party (SQ) in Enkoping, Assange deliberately consummated sexual intercourse with her by improperly exploiting that she, due to sleep, was in a helpless state.
It is an aggravating circumstance that 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, still consummated unprotected sexual intercourse with her. The sexual act was designed to violate the injured party's sexual integrity.
Offence 4, Page 3 of the above document.
The lack of a condom used also shows up in Offence 2, Page 2, for a different injured party (AA).
How about you Assange supporters actually get your facts right about what the arrest warrant actually lays out? You can harp on about "such silly charges" but its patently obvious you have never actually read the rulings against Assange, which makes it trivial to dismiss you out of hand.
