Id argue that rather than him exposing the class as a hoax, he exposed that his level of comfort with the course content was quite low. The class is about emotional intelligence, and he essentially admits he is lacking in this (not able to understand why his actions provoke certain responses in people).

I've taken a similar class, and the content can be quite uncomfortable (and sometimes the content strays into bs territory, but I and others find much of the content of value). A common reaction to this uncomfort is to deny the validity of the concept of emotions / EQ, but many people who try to understand these concepts do come out with a better understanding of how to engage emotionally

I know for many logic minded people the concept of emotional intelligence seems like bs, but it is real (sorry for asserting this rather than providing evidence, but that's another topic). My brother is on the spectrum and I'm on the autistic side of normal, and it's my experience that EQ can be learned and that learning it valuable and worthwhile personally and professionally
