I hear you about gym teachers. They could at one time be blamed for turning a lot of people off exercise with their relentless touting of competitive team sports over general health and fitness. But most educators, until recently, used shaming to some degree to supposedly create motivation. The shaming by teachers in the 1970s that I remember as a teen would take your breath away. It was a toxic practice that thankfully has been loudly condemned in 21st-century education. Hopefully your beautiful daughter will never experience the negativity that you experienced. You deserved better.
