If you are offended by any of gjm's statements, I suggest you walk away now, because what I'm going to say is going to be just as offensive to you as anything that gjm has posted.
Right, I take issue with your statement that autistic people are irrational, but I think that point has already been made for me. What I am taking issue with now is:
then I think that's a sad state of affairs.
You believe it is a sad state of affairs that people on LessWrong are discouraged from discussing topics that will harm people more than benefit them? Am I correct in therefore saying that you believe it is a sad state of affairs people on LessWrong are discouraged from doing stupid and irrational things? Because if so, that doesn't seem like a sad thing at all.
Consider the case where political commentary is viewed as just as acceptable a topic of debate as any other. Yes, it would be ideal to have everyone here so rational they can discuss politics freely, without risking harm to their rationality. Yet it is a fact that Politics is the Mind-Killer, and this is not going to go away and it is not going to change because you believe in freedom of speech. And I don't think this is a particularly sad state of affairs, for the very fact that people avoid things that make them irrational is a promising sign that they value their lack of bias.
But you seem to think that the freedom to say silly things like "autistic people are less rational than others", or to bring up disruptive topics, outweighs that consideration.
At this point, I would like to recommend that you close the window right now, turn away from the computer and think hard about whether complete freedom of speech is one of those things that, in the minds of some people, automatically equals a win. I can't recall the technical term for it, but I do recall quite strongly that it will kill your mind.

I notice you didn't make a similar to reply gjm with respect to his being offended by Dahlen's comment, even though gjm's offense was much more irrational.

That is not a silly thing, it is in fact true for most definitions of "rational".
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.
