Really, the point I was making is that it's not interesting to judge someone by an individual act - from a social point of view it's far more important how someone deals with having fucked up than how often they fuck up in the first place. What primarily distinguishes a neurotypical from someone on the spectrum is whether they can identify whether a given act is going to be offensive in advance, not whether they modify their behaviour to avoid identical behaviour in the future.
The biggest problem people on the autistic spectrum face is generalising from a specific item of behaviour to broader behavioural aspects. People with no experience of working with those on the spectrum tend to generalise this into a complete inability to learn, which leads to positions like Bruce's implied "It's not their fault if they offend people, no matter how often they're told it's offensive". When we look at the specific case ("Don't make the joke about taking women's emacs virginity, it can be interpreted in a variety of unfortunate ways"), suggesting that it's not RMS's fault if he does it again is entirely inexcusable. I'm genuinely upset at the implication.
