It's not all millennial, but a growing subset of them that has this issue. Maybe it's a byproduct of helicopter parenting where they're insulated from the harsh world of mistakes and consequences. Having a parent call in to complain about feedback an employee receives used to be pretty much an urban legend, yet now it's rampant. There's also the ridiculous test-driven culture of schooling, an artifact of the absurdly misguided "No Child Left Behind", where numbers and scores matter far, far more than any actual understanding. Criticism in the form of lower grades can be really damaging to someone's academic career, so no wonder people hate it so much. Decades ago you could squeak through into the program you wanted with high grades and make up the difference in terms of passion for a subject. Now if your grades aren't perfect, you'll never get into competitive programs. What kind of a system is that? When you're conditioned to think that any mistake you make, no matter how minor, goes on your permanent record and may steer your life completely off course, you get a bit touchy about it.
