The opening post certainly does feel goady to me. Such lack of awareness on this thread.
This discussion is however a good one to have and I welcome debating posts, if the intent is to debate of course.
I participate in parenting threads primarily as I have experience. I will regularly suggest ND as an explanation. I know I'm usually right.
To answer, parents in this situation tend to pick up on cues within posts that other people won't get, receive or resonate with.
There's significant misinformation and lack of awareness. For example, the overwhelming inheritance rate. A poster will almost always declare further along that a close family member is ND. Most people are unaware of this heritability factor.
There's a political agenda underway utilising smoke and mirrors nonsense such as suggesting people are being ' over diagnosed '. No,they aren't. But it's a bit like 'they're eating the cats and dogs'. The public must find a scapegoat.
Reality is, people are being MIS diagnosed more likely with things such as ' borderline personality disorder ', depressed and anxiety, when really they needed an Autism assessment. But a thorough NICE approved assessment isn't easy to access anymore. And service provision is actually being obliterated.
So, people will be Autistic and unable to access assessment which you will use to further justify your own need to believe this story being fed to you. 'oh everyone's self diagnosing '. Personally, I didn't ever meet anyone who suspected they're ND and then myself thought they were wrong on that suspicion. Not a single one.
The truth is - the ND population is significant. ND people are having children and those children are likely all going to be ND. The public clearly does not like this.
People can be ND and also be dicks. As can NT people. This post, the media and others are an attempt to over simplify something. I never see posts such as ' my husband hits me ' and a reply such as ' is he Autistic '. Never.
ND behaviour will be difficult quite often for NT people living in an NT world with fixed social rules and quite bizarre approaches to schooling as one example. People are being set up to be difficult.
