By definition, only the arbiters of the legal system itself, i.e., the government can deprive someone of due process. The fact that Sweden and the UK are making a sincere effort to extradite Assange is, at this point, all the "due process" the women are entitled to. Assange's actions have nothing to do with it.
"He said "Wikileaks stands under threat" - that's not true at all, at least not in the way he thinks. Wikileaks is not Assange. Assange is under threat. He is conflating the two."
Buying the argument that the charges are politically motivated, the fact that they are attacking Assange due to his association with wikileaks mean that wikileaks is under attack. If this sets a precedent that high profile persons leading the push for the release of extremely sensitive information can be rubbed out so easily puts a chilling effect on whoever steps into Assange's place. And that's assuming anyone really can just step up as Assange didn't just start with wikileaks. He's been involved in uncovering suppressed information since he was a kid growing up in Australia and even co-wrote the Rubberhose deniable encryption program.
It's telling that someone like Assange who is undergoing such a massive level of scrutiny that these rape allegations are the best they can do. The guy must practically be a saint.
