I get where you are coming from (and take no offense). If I understand your intent correctly, you are right that I should be more generous to teachers. In the context of larger educational challenges (and a recovery from the pandemic), I did not mean to suggest that teachers’ intimate familiarity with Shakespeare should be a high priority in our schools, merely that in a perfect world (without other challenges), students would learn Shakespeare better (which I think would be a benefit) from teachers that know the material.
Sadly, our educational system has much deeper challenges than that, and I didn’t mean to suggest otherwise. The conversation was about Shakespeare specifically and how his works are taught, not the broader state of education.
