"ATM Machine" Plot Twist: Pathology of Grammar Policing - TO BE CLEAR, the message here is NOT that grammar policing itself is an OCD or ODD. The "physiological element at work" is in reference to physical or mental impact that language may have on SOME people akin to OCD/ODD but could very well be rooted in other conditions. This video is not a mental health diagnosis (mental health is not my expertise) but an analysis of a behavioral pattern that can be the manifestation of various conditions.
