A Mother's Perspective
First, the introduction uses personalisation, ie, the belief that a general statement or statements is intended to hurt a particular person or group of people in particular. This is a logical error often seen in Neurotypicality, and said to border on psychosis.
Additionally it uses specific wording to attempt to elicit sympathy for Kit Weintraub by portraying her as a desperate fighter for the forces of good, which is obvious dramatising. This NPD trait has been used to suggest a possible relation to Histrionic or Bordeline Personality Disorder.[Note, the introduction was not written by Kit Weintraub, but by an editor. This editor may also have NTD and/or NPD.]
Then Kit Weintraub begins. She first makes a meaningless distinction in wording, and then misrepresents the history of that type of word wrangling and misrepresents the reasons the wording she dislikes is used. The latter is probably due partially to the egomania of NPD and partially due to the speech problems caused by NTD. The first is probably mostly due to NTD.
Then she distorts the truth in claiming:
a) that Ms Dawson and similar people are all self diagnosed, when many have been diagnosed by prominent experts in the field of autism, and
b) that they believe autism does not cause difficulties in functioning, when they have often spoke about these difficulties and many are in desperate need of assistance for these difficulties.
This is probably due to the tendency of people with NTDs to lie, although it may be due to poor comprehension.
Then she does exaggerated personalisation, claiming that Ms Dawson et al portray parents who use ABA as 'selfish perfectionist control freaks(shades of refrigerator mothers!)' and professionals as 'cold manipulative child-abusers'. Most likely this is due to both NPD emotionalism and NTD social impairment, although there may also be an element of lying involved.
The next paragraph is surprisingly truthful considering the earlier paragraph, although it does mention the belief that personally attacking Ms Dawson will somehow help her children and other autistic children. This is possibly a combination of dramatisation and personalisation. Also note the assumption that Ms Dawson, due to her writing ability, is not very similar to Kit Weintraub's children. This is probably part of the NT social delusion.
The third paragraph, rather short, is a clarification of the earlier one. She confirms that autism exists on a spectrum then turns around and claim that because of perceived differences between Ms Dawson and her children, Ms Dawson is not autistic.
Then she demonstrates defensiveness towards the perceived claim that she doesn't love her children. Oddly enough, she contradicts that by expressing dislike towards an important part of her children. The first is an example of the social impairment, the second is egomania conflicting with natural mothering instincts(ie, her NPD makes her dislike differences, but her mothering instincts tell her to love her children, so she decides to love all of her children except for their differences).
Then she misrepresents what normal actually means(NT with comorbid NPD) and claim that it means 'a cookie-cutter child, trained to do my will'. That is a dramatised version of what trying to make a different person normal produces, but it is not what true normalicy is. Then she claims that normal=able, when there is clear evidence that abnormally intelligent people are able but not normal. NTD language and social deficits, along with NPD egomania, are probably behind this.
Then she claims that her children's autism is either a gift or a disease, evidently an example of black and white thinking, common in NPD. And as is typical for those with NPD, she assumes it is a disease. She also assumes that by saying autistic people are not defective versions of NTs, we are saying they are normal. This is probably due to both NTD(assumption that what she wishes to be though of is what autistics wish to be thought of) and NPD(which causes the desire for normalicy). Additionally she assumes her children would not have developed the skills they have if they had not been in ABA. As someone once said, a study with 1 or 2 subjects and no control is not scientifically valid(paraphrasing, this person reffered to it being laughed off).
Then she uses dramatisation while talking about regression, and assumes that Ms Dawson doesn't understand regression(she knows several people who have regressed). Perhaps the second is due to NTD social skill deficits.
Then she assumes what Ms Dawson would feel about medication(In fact many of the people in the autistic community use medication to help with various problems, including self-injury). This is obviously the NTD social skills deficits(LoToM).
Then she implies that the fact that her daughter loves her therapists and her children have not experienced adversives means that adversives and serious emotional harm never occur in ABA. This is similar to claiming that because you don't sexually abuse your children no one does. It's probably caused by social impairment, although lying could be a factor.
Afterwards, she claims that her son's quirkyness doesn't bother her, but contradicts that by saying that if she could, she would remove this quirkyness. Most likely this is NPD.
Then she overgeneralises Ms Dawson's argument to include life threatening situations such as illnesses and refusal to eat, and harmless treatments that are medically proven to prevent illnesses. It's likely that overgeneralising is an NTD trait. Then she again demonstrates personalisation by claiming Ms Dawson condemns parents and professionals.
Then she expresses the expectation that someone disputing a treatment should have a pat answer to an alternative. It is not necessary for someone to provide an alternative if alternatives are already available(Son-Rise, Floortime, etc). This is probably NPD, the desire to have someone else think for them which is evidenced by fads.
PS: This is a joke, to point out the errors in their arguments in a humorous way. I am not saying that they are disabled, although I believe NPD is definately a disability. I am just doing a parody.
