It means ikosmos, that you are calling a woman who said she was held down and raped a liar.
And another woman who accuses that she woke up to find Assange on top of her.
That's what you calling these accusations "fabricated" and "character assassination" means.
From the 2012 court process, which I linked to above:
“[The complainant] was lying on her back and Assange was on top of her … [she] felt that Assange wanted to insert his penis into her vagina directly, which she did not want since he was not wearing a condom … she therefore tried to turn her hips and squeeze her legs together in order to avoid a penetration … [she] tried several times to reach for a condom, which Assange had stopped her from doing by holding her arms and bending her legs open and trying to penetrate her with his penis without using a condom. [She] says that she felt about to cry since she was held down and could not reach a condom and felt this could end badly.”
The only character assassination going on here is your linked blogger repeating Assange's claim:
Her behaviour towards me on the night in question and in the morning made it clear that she actively and enthusiastically wanted me to have sex with her.
That's "Well, she wanted it, so it couldn't have been rape" if it needs translating.
I said already that the U.S. and Sweden are obstructing this case, and that Assange has every right to complain about his de facto arbitrary detention, because it is obviously a ploy.
So why is he also trying to undermine the women accusing him? They played no part in what the U.S. did.
Probably because he'll do anything to try and save his own skin, including misusing the organization others have trusted him to use to tell the truth.
And the fact that he has marketed his get out of jail campaign by calling women "bimbos" shows where his scruples are when it comes to misogyny, sexual assault, and using the reputations of women to his own ends.
