I believe the problem there starts with calling that a “parent” instead of an insufferable grown-ass child who assumes they are never wrong, and is hell bent on perpetuating that mentality at the expense of their own children. Those are the offspring who rack up a dozen job firings before they reach their 20s, and are still wondering why everyone else has a problem, because never-wrong.
Most certainly. I've had college professor say parents call to complain about grades.
And while I understand you wish to table this as also a conservative problem, that becomes quite moot when 90%+ of American educators at every level, are undeniably liberal. Higher education has become a political indoctrination in America now, and with that kind of imbalance represented in educators, the liberal influence and resulting product is blatant no matter how Red or Blue anyone feels.
Well, the Heritage Foundation paints a different picture of K-12 educators from a 2021 survey:
A nationally representative survey of K–12 teachers does not support the idea that America’s public school teachers are radical activists, although conservative and moderate parents may find it disconcerting that nearly six of 10 teachers believe that white supremacy is a major problem in the United States. The survey results indicate that, while teachers tend to be somewhat left of center on many topics, their responses were not particularly close to positions held by the average liberal. Overall, the results could be welcome news for parents who are concerned about the growing influence of progressive ideology in public schools. Teachers may very well be allies, not opponents, in the pushback against the application of critical race theory and other divisive ideologies in the classroom.
While they may tend to the left of center a bit, they appear to be more moderate than how some portray them for political purposes, and have a significant % who could be considered conservative.
