Oh it's almost certainly disinformation to some extent. He's not really discussed it at all (and definitely not under oath) so it's hard to draw any real conclusions about whether or not he's a rapist.

However he's almost certainly a complete cock to people on a regular basis. There's a lot of evidence for that. Just because you are totally awesome at one level of social discourse doesn't mean you aren't also a complete bastard to people on a personal level.

For very narrow values of "wide". FWIW, you're linking to Assanges own assertion that it's a smear campaign.

If this was a smear campaign orchestrated by the top echelons of the US intelligence/military complex, they would have done it better. If they're out there twisting arms and making up charges, why not make it a proper rape, not this "well, strictly he should have known she didn't really approve even though she didn't say anything at the time"-business.
