Bashing or not, an analogy to the claim that teachers need to fix the mess that is pandemic learning: (context/inspiration: my dad is currently furloughed from his usual job and is working as a clerk in the produce department of a local grocery store)

Grocery store customer: I want apples!
Clerk: I’m sorry, we are all out. We have oranges and bananas.
Customer: No! I want apples!
Clerk: We might have more tomorrow, we ordered them. Sorry for the trouble.
Customer: it’s your fault! You took my apples!

Clerk: I haven’t been able to buy apples either. It’s very frustrating.
Customer: but (other store) has apples, you need to have apples for me too!
Clerk: I wish we had some, but we’re all out today
Customer: it’s your fault, shame on you! You’re a terrible person!

Customer: *throws orange at clerk’s head*
Clerk: *is expected to smile and nod*

The grocery store clerk isn’t at fault for a supply chain problem of no apples in the store. The teacher isn’t responsible for pandemic learning being suboptimal. There are systems at play. The problem is the problem, a chosen scapegoat isn’t the problem.
