Regardless, I think Stallmam's mistake was to try to start a debate about Minsky's guilt and about statutory rape in the wrong place: a mailing list about Computer Science which includes both staff and students, especially given that he is not a random person, he is an authority figure when it comes to CS and at MIT.
The debates might be valid but the place, and time (given everything going on about the connections between Epstein and the MIT) are what is wrong here.
