As a linguistics professor I would say that the posts by "Michaels" and "his wife" are stylistically identical. Notice the use of caps, the double periods (..) and slightly odd grammatical phrasing. Of course they say that married couples start to sound alike after a while but I too find it highly unlikely that any mother who actually had an autistic child would EVER refer to him or her as "retarded."

There are just dozens of linguistic and social red flags in everything "Michaels" has posted here. And as I said early, there are just way too many other kit cutters in the US to put up with this sort of thing.
