Great post, Callista!
I recently saw a small boy having a melt-down outside the supermarket. I could see he was trying to pull a toy out of the bag in the tray under his sister's pram. I went over and squatted so I was his height and calmly asked him if he wanted the toy. I asked him if he had asked his mummy nicely for it. He stopped sobbing and looked at his mum, and said "Please". She simply said "No." So I explained to the lad that it would not be a good idea to take the toy as it could be broken or lost on the way home. He accepted that, and turned to his mum for contact. She, poor thing, looked exhausted. I told her that I have four autistic sons, and they all need proper explanations. I hope that I helped her more than all the other passing shoppers who had tut-tutted. Her face was a picture. I wonder if she had thought of autism before, because her expression wasn't one of denial that her son could be autistic; more like "If a stranger can see he's autistic, perhaps I need to take it seriously" Or perhaps I'm not very good at reading facial expressions!

She certainly didn't argue with me; indeed she simply left, looking thoughtful (and very, very tired).
A little while later I saw an NT child throwing a tantrum outside another shop. It was quite obviously the behaviour of someone well aware of the effect their behaviour was having on the accompanying adults; both of whom were treating the display with good humour and a refusal to give in to the demands (again a dispute over a toy, this time one the child had brought with her and no longer wished to carry).
I was a little surprised by the title of the original article. I had got the impression that a lot of modern parents were brought up as little princes and princesses by permissive parents and simply couldn't cope with the idea that the world doesn't actually revolve around them; & that their children won't accede to their demands the way their parents did. I think now that I was being a bit harsh. Raising any child is hard work and I think that the popular view (encouraged by advertising and entertainment) that it should be easy and predictable does no-one any favours.
I just didn't think that parents were 'hidden' victims because all the propoganda I have read recently has been weighted in favour of the parents being 'victims' of their child's autism; rather than the child being a victim of misplaced expectations and wrong (for an autist) child-rearing practices.
