I'm fairly sure it was sarcasm, since that's sort of a kneejerk reaction that coders have to people with issues, and in this case it's completely absurd.
I've noticed that techies have a tendency to drift into absolutist thinking, probably because we're so isolated from mainstream society, so our brains, being the wonderful bayesian-esque learning machines they are have relatively a relatively small sample of non-diverse data on the subject. And the abstract world we work in is artificially absolute. And maybe it's partly the type of person that's drawn to this field.
Which is just a complicated way of saying that we're often really crappy at modeling the real world in our heads unless we've forced ourselves to get out there and gather some experience.
