Autism is not literally what I meant
Then I suggest that perhaps you should have chosen some other term than "autists".
lacking a module [...] does not signal superior cognitive functions to me
Sure. But I didn't say "It appears that you think autistic people are not cognitively superior overall to the average person", and that's because that isn't what I meant.
The lack of a skill is the lack of a skill.
Awestruck as I am by your insight, I feel it necessary to point out that not all skills are the same, and that "not being good at some kinds of intuitive understanding of other people" is not at all the same thing as "being less rational than average".
It's not clear whether the last sentence of your comment is (1) just reiterating how important it is to you that autism be regarded as a cognitive deficit or (2) intended as a comment on FrameBenignly's proposal that the topics s/he listed are poor choices for LW. If #1: OK, fine, but that has nothing much to do with anything. If #'2: if you think, or are pretending to think, that FrameBenignly was proposing that the topics s/he listed are poor choices for LW because the people here can't understand them then I can't agree; I think the reasons were more like "because discussing X tends to produce more heat than light" and "because talking about Y is liable to offend people and the benefits aren't worth the offence".
Sure. But I didn't say "It appears that you think autistic people are not cognitively superior overall to the average person", and that's because that isn't what I meant.
A common definition of "rationality" around here is "the art of winning", by that definition I don't see the distinction your making.
For example, what would be inappropriately off topic to post to LessWrong discussion about?
I couldn't find an answer in the FAQ. (Perhaps it'd be worth adding one.) The closest I could find was this:
However "rationality" can be interpreted broadly enough that rational discussion of anything would count, and my experience reading LW is compatible with this interpretation being applied by posters. Indeed my experience seems to suggest that practically everything is on topic; political discussion of certain sorts is frowned upon, but not due to being off topic. People often post about things far removed from the topics of interest. And some of these topics are very broad: it seems that a lot of material about self-improvement is acceptable, for instance.
