If you are offended by any of gjm's statements, I suggest you walk away now,

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.

But you seem to think that the freedom to say silly things like "autistic people are less rational than others"

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