He may be the most disabled one of us all but he's here voluntarily and he's an adult. If he'd prefer to be a little less of a target, a good first step would be to stop with the commentary on us poor autistic folks. Remember when his posts actually made some sense, when he took his meds, and we picked him as the newsbox feature? I don't recall people targeting him then, probably because his behaviour was a lot better.
He's fair game, in my book.
