I suspect many of your upvotes were simply for offering a link to the interesting and post-related concept of depressive realism.

A good joke is both informative and funny. Those who get the first contrarian level of the joke, depressive realism as a counterpoint to ksotala's arguments, will learn something; those who get the second level, the claim of depressive realism being related to Yvain's neurological oddity, will both be educated and be able to interpreted ksotala's post as an example of the backlash, which is very funny. (All in one sentence too.)
