A couple of thoughts on this excerpt from your reflections :" I assume it was the norm in previous decades." Sadly in my public school k-12 experience (1962 - 1977), this was far too common a tactic of disreputable substitute teachers of questionable degrees and training. Derogatory name-calling is an attention-seeking, bullying behavior which always says more about the speaker than the recipient. Thank you for the opportunity to comment.☮️🌍🌏🌎☮️
