Thank you for making this point. It's somehow been mostly lost in the noise of this thread that the main reason RMS's comments are so unacceptable is because he gave this defense (theoretical or not) of someone accused of having sex with a child trafficking victim. Not because he happens to have socially unacceptable opinions about certain corner cases in consent laws. Fortunately in this case, there's a very very bright line, and RMS was way over it.
I mean, his defense was of Minsky, not Epstein. RMS believes that Minsky likely wasn't aware of of either her age nor the coercion so Minsky could hardly be blamed for not knowing. I haven't followed this too closely (except on HN) but I think that incident also predated Epstein's first trial (conviction?).
I suspect (and really really hope) RMS wouldn't have such a defense for Epstein himself.
