Public school is a gift , the teachers are a gift and a blessing. Yes there are imperfections in both , yes there is social stratification tendencies, but that’s the proper attitude about school.
Scaredy, I can’t imagine you raising your kids to have a bunch of excuses and behaviors that totally trash the gift and disrupt it for everyone else while making their own futures much poorer. Maybe you can’t relate , have you ever tried to survive an excessively hostile school room environment when the harsh came from the kids? Why make excuses for someone else’s kids? Because those excuses hurt everybody. What is it, low expectation for them? Hate?
