There's a lot of boomer men writing in all caps whose special interest is either trains or WW2 who, if were in their 20s today, would easily be categorized as autistic. Older men, for most of their lives, lacked both language and social permission to think of themselves in those terms.
The entire construct of "disorder" is defined by what a given society is willing to accommodate or tolerate at a given moment. Thus, the problem with the article is that it assumes that we live in a homogeneous social landscape. We don't, so things that negatively impact someone life ie: the definition of a disorder, are age dependent. The threshold for "impairment" is not a universal biological constant; it’s a moving, socially negotiated boundary. Diagnostic categories themselves are historical artifacts, trailing behind the societies that create them.
The failure to recognize this is assuming an objective social reality, that frankly, never existed and never will exist. It only serves to reinforce existing, unexamined, contingencies of a specific time and place.
