I didn't have a problem following them [AFAICT, there's nothing particularly complicated about the subject], to me the content structure lacks hierarchy that others naturally apply; rather like unintentionally burying the lede. Their point seemed like it was 'left as an exercise for the reader' -- fine if they intended that style is prose.

I didn't blame the GP; friends who have conversed with me in that manner (only 2) have had diagnoses of Asperger's [which is why I chose that term over ASD].

FWIW there were several interesting things in the comment, and I'm glad they made it.
