Stallman was not saying that Minsky should not be absolved of responsibility. He was just saying that the term "sexual assault" is inaccurate in that it implies violence.
> I think Minsky was smart enough to know what was happening.
That's a fairly large assumption. Minsky's name shows up twice in hundreds of pages of deposition. Once is in a statement by the victim when she is asked to name names:
> They instructed me to go to George Mitchell, Jean Luc Brunel, Bill Richardson, another prince that I don't know his name. A guy that owns a hotel, a really large hotel chain, I can't remember which hotel it was. Marvin Minsky.
And the only other reference (that I am aware of) is in reference to being on a private flight with a bunch of other people.
How are you able to infer so much from so litte information?
