In fact, the idea that autistic individuals are immune to propaganda is, itself, media propaganda. The study that those articles report on was a single study that found that autistic individuals show less of a framing effect on their own preferences. It's much more easily explained by autistic individuals having strong, internal preferences for their own likes/dislikes than it is by autistic individuals being immune to propaganda.
