While I sympathize strongly with people who have been bullied, or who have heard painful things said to them or about them, I have heard not a scrap of sympathy for the people in this film and what the anguish that they have had to go through.
Why feel sympathy for somebody who talks about how much of a burden their innocent three year old child is to them, how much they cost, how they're never going to be good enough an how they wish they could kill them. If these parents were genuinely stressed and confused (as it must be trying to raise a kid with different neurological wiring to you) but didn't badmouth or undermine their children or play the pity card then I might feel sympathy for them.
Mostly what I've seen instead, again is, total self-absorption, and ludicrous attempts to impart the worst possible motives for both the producers of the film, and of the people who share their feelings in it.
Do you not think the parents who were sobbing to the camera because their child wasn't going to be in a school sports team were self-absorbed and ignorant? How about te parents that blatantly said- IN FRONT OF THEIR AUTISTIC KIDS- That autistics shouldn't exist, and that it woud be a happy day when technology was found to wipe them out.
One thing this film tries to do is break through that, to convey the reality that autism in a family extracts an ENORMOUS cost on everyone else in it.
It doesn't have to. Half the expensive therapies parents remortgage the house to have are unnecessary. In fact I believe the intensive stuff is downright cruel. Autistic children are still children, and should be allowed to have a childhood.
Most of the problem comes from parents who are obsessed with making their children normal. Wouldn't they be better off teaching their kids to be proud of who they are? Also autistic people often adapt to society on their own, in their own time.
And the parents in the film kept forcing their young kids to do things they didn't want to do for long periods of time- and then wondered why they got distracted or whiny. They blamed the autism.
Autism isn't the cause. I challenge you to get ANY toddler to sit down and do a jigsaw with you when they'd rather be doing something else.
And the motive is NOT to make people with autism feel bad about themselves, but to impart a sense of urgency in researchers, donors, policymakers, and the general public about finding such a cure.
Most people on this site are against a cure for autism, so that argument just isn't going to hold any water. Why would we see your point of view if it's supporting a cause we don't agree with?
Bizarre paranoia about mass-abortion plots does not reflect well on those who engage in it.
I agree that some people on here do panic a bit over this, but don't dismiss it. Many people are progressively working towards something that many of us see as genocide against us. Why wouldn't at least a few of us be worried?
NTs need social interaction, warm feedback.  It hurts terribly when a child doesn't smile, doestn't coo and play, doesn't talk.  It hurts terribly when the high hopes that one had for a child are replaced with the grim realization that to get to the same place will require a mountain of effort. That's NOT "bigotry" or "ignorance" - it's an expression of a completely understandable pain at experiencing cruelly dashed expectations.
I understand that it must be strange, but bear in mind that it doesn't mean your child doesn't love you- they're just not that good at showing it. Try and work out alternative methods of communication- get into your child's mndset as best as possible.
The best way to get around the dashed expectations thing is to not have expectations for your child in the first place! It isn't fair on any child- autistic or otherwise- to feel that they have to live up to goals their parents set them when they were babies, and feel like failures if they don't.
You sound like you think a parents is well within their rights to think that their autistic toddler isn't good enough becasue they're unlikely to be in a sports team/may need to go in special ed/Stim.
A young autistic child may not be what you expected, but they haven't done anyhing wrong! They aren't being autistic just to spite you! It is unfair to traet them with contempt just because they didn't come who you'd expected them to. Children aren't dolls, after all!
And calling for punishing a child for wishing that he sister were not autistic just leaves me speechless.
As other posters have said, replace 'autistic' with 'gay' or 'ginger' or 'left-handed' and you'll see where the problem is.
I do think punishing the child is a bit harsh though- she'd only young and probably wonders why her sister doesn't want to play with her. She just needs to be sat down and taught that there is nothing wrong with her sister, and get given ideas on how she can spend some time with her.
