Just read all 16 pages of it and feeling very uncomfortable as I can see points on both sides.
I do think that in some cases the 'professionals' are taking a lazy approach by not discounting other possibilities (as they should do) before arriving at the ADHD dx. And we know from our own experiences that the competence of professionals varies considerably.
I don't see the point in multiple overlaping dxs - my DS with Aspergers displays a lot of ADHD behaviour - insomnia, can't sit still etc etc but these behaviours have their roots in his primary Aspergers dx i.e. insufficient melatonin secretion, fidgetting because of physical discomfort in room of strangers, because of sensory issues etc.
And I recognise that all these conditions are part of an overlapping spectrum.
But I do agree that in our child-centered society behaviour that would not have been acceptable years ago is now becoming more common.
I do think that drug companies are 'pushing' medication. I have concerns about some ofthe universal 'cure-all' drugs that are being (over) prescribed - where the same anti-pschyotic is used to treat conditions as varied as anorexia, schizophrenia, anxiety disorder. OCD etc.
Having said all that...
I do believe that ADHD exists and that it's not the result of bad parenting.
I just don't think we needed to rubbish the OP's views quite so forcefully - perhaps we should have walked away and let it slide to the bottom of the page and oblivion.
Not our finest hour
