Evidence that the term "microaggression" survives in public discourse (at least at McGill University in Canada). Here's my speculation, dated December 13, 2013, that the word had died:
I've been working on the theory that the term "microaggression" briefly spiked to prominence and then utterly crashed with the story of the professor who was accused of "microaggression" for correcting spelling and grammar errors....I reported a blip of usage there, but then, on January 6, 2014, after checking for signs of life, I proclaimed the term "really most sincerely dead." I've kept monitoring and today's link goes to Professor Jacobson who asserts:
“Microagression” is the latest craze in racial grievance, something we highlighted when a UCLA professor was accused of the transgression for correcting grammar on minority students’ papers.That is, as evidence of the "latest craze," he cites the very incident that I saw as so dumb it killed any incipient craze.
By the way, the idea of microaggression is a secular version of the scrupulously religious believer's concept of sin. There are all these little wrongs you might be committing, and you should become aware of them and apply conscious effort to eliminating them. The religious person might believe that God watches and cares about these tiny infractions. The purveyors of the concept of microaggression seek to instill a conscience about the smallest things, but unlike those who define sin very broadly and call believers to seek perfection, they are shaming even those who have not yet signed on to the broad definition of what counts as wrong, and they want to enforce their strict demands through the exercise of power in this world.
