Epstein's island wasn't some stereotypical villain lair where anyone who steps foot on it must be up to no good. It was a place that he conducted the normal business that any entirely legitimate billionaire would conduct, in addition to the villain stuff.
Based on the girl's deposition, it looks like she was there on the record to provide massages to guests, and off the record was forced to make those erotic massages including sex. It is not clear which, if any, recipients of those massages plus sex knew that the sex was something she was forced into. There are no details given on her sex with Minsky other than it happened.
This isn't applicable to the specific case of Minsky, but I think that ambiguity evaporates after Epstein's first conviction.
The allegation about Minksky stems from a single line in a gigantic recently published deposition ( https://twitter.com/_cryptome_/status/1159946492871938048 ), covering events long before 2008.
Minsky was included in a list of people that Epstein's assistant asked one of his victims to have sex with (the deposition didn't ask if sex actually occurred). In the deposition the victim couldn't remember the date they received that request, but a third party reported that they saw the victim approach Minsky in 2002 and that he turned her down and complained about it ( https://pjmedia.com/instapundit/339725/ ).
It may be the case that the witnessed event and the content of the deposition were unrelated and at different times, but if not-- the victim was also 18 at the time...
But no one really cares about the facts, this is almost entirely a ceremonial battle over who has the sickest imagination. Because there are essentially no clear details, not even a concrete allegation, everyone is essentially making things up in order to fight over them.
> Epstein’s former neighbor, the psychologist and computer scientist Roger Schank, describes another such event that he attended: a meeting of artificial-intelligence experts, organized by Marvin Minsky and held on Epstein’s island in April 2002. “Epstein walks into the conference with two girls on his arm,” said Schank. The scientists were holding their discussions in a small room, and as they talked, “[Epstein] was in the back, on a couch, hugging and kissing these girls.”
