This is funny, but true. But like everything, there are a bunch of reasons why this happens and it's not just snowflake syndrome. If anything, one of the reasons is because Gen X and the early Millenials are more competitive than their parents and actually care about the "wins" in school instead of just accepting their kids for who they are. Then there's the fact that college admissions have become more competitive and so more is on the line and there's a greater demand to be perfect.
True story: my parents never interfered with my education (even against a nun in 6th grade who was border line abusive but in the end taught me a great deal about responsibility, personal commitment, and excellence) until high school. My freshman year of high school, I had a teacher who was a full blown socialist whose first 4 weeks of European history lessons were social justice issues (contemporary, not historical)...week 2 was a lesson on how US agribusiness was ruining Latin America and we needed to go back to the days of community (read peasant) farming....rather than regurg the rubbish, for the example I presented a defense about how (even though it has negative consequences such as pollution, poverty and migration to the cities, which I expressly referenced) mass agribusiness was actually responsible for increasing farm yields throughout the world....pretty balanced approach, highlighting the positives and the negatives, as well as what could be done better. She flunked me. My parents were livid and it was the first time they ever called a parent conference to discuss a grade. Teacher tried to argue I didn't understand the material and she was grading me on my failure to memorize, rather than my rebutting her political views. My father, to his credit didn't take it and questioned up to the principal why we were even learning this material instead of what's in the history book. Given what's on the line now days, I can't see a parent allowing the same situation now days without calling in the lawyers. And I couldn't see the same school allowing the teacher to go off on the rails on a private political agenda instead of teaching the curriculum (yeah, I know both red states and blue states put indoctrination into the curriculum now....how else is indoctrination going to get into schools).
So yeah, but the days of people just deferring to authority, for better or worse, right or left, are pretty much over. That extends to soccer too, which is why you get so many noisy questioning parents which are the bain of coaches' existence.
