It's terrible to read, and yet... It's so hard for me to pity teachers when I see these anecdotes, time and time again, and increasing in recent years.
In college, I had been friends/acquaintances with many students going into teaching. They all shared the exact same philosophies: there are no bad students or bad kids, only teachers who were too lazy to modify curriculum to make sure each student succeeded; no child should be left behind; grades, homework, and punishment should be lax and take the child's personal situations into account; liberal and progressive sensibilities must be pushed; and of course, THEY could do much better than those complacent, tenured teachers they had.
I've since watched all these philosophies blow up in their face. Some kids ARE just plain retarded and refuse to learn, no matter how much they tried to gently correct them. Discipline IS needed to correct behavior, and homework IS necessary to learn and retain information. Replacing Shakespeare with the most recent Shanequia whose DEI book is the flavor of the month is a bad idea, because Shakespeare's works have lasted this long for a reason. Worst of all was seeing how hard they all fought for schools to be shut down as long as possible during COVID. Now we have an epidemic of nonverbal, screen-addicted young children and teenagers with the attention span of goldfish, and young adults are majorly pissed and entitled that they lost some formative years to the pandemic and take it out on everyone else.
Social media and terrible parenting are also to blame, and I would never argue otherwise, but when you maliciously fuck up some basic fundamentals and principles of teaching because you personally disagreed with them, other things are bound to fall apart.
