"Can retroactively withdraw consent" - bullshit, this is not an accurate description at all. I think this quote sums it up well:
"The New York Times reported that the two women claimed that "each had consensual sexual encounters with Mr. Assange that became nonconsensual.""
Basically, they started have sex, she said, "Okay, time for the condom!", he said, "Condom, schmondom" and proceeded against her wishes. Sorry, folks, but even after everyone has taken off all their clothes and are getting all snuggly, it's still possible to commit rape. Just imagine any number of things you would not like to have done to yourself while naked in bed. Go on, I'm sure you can think of something. Now imagine your next sex partner decided to do them to you and wouldn't take no for an answer. Also imagine that your sex partner is bigger and stronger than you and a worldwide hero and that thousands of self-righteous internet commenters will come to their defense.
If you think this is an okay way to have sex, do, please, post your name and photo so we can avoid you just as assiduously as Julian Assange. Thanks.
