If a lot of people are telling you how to do your job (and parents insisting that their children should receive in-person education isn't really in that category), and you're this defensive about it...
You are pretty much admitting that YOU don't even think you know how to do your job.
“I am so sick to my stomach of parents trying to tell educators how to do their job.”
My children graduated from the San Francisco public schools and succeeded despite them, but all I heard from the teachers during that time was them telling ME how to do MY job. Good thing I didn’t listen.
