The school just released a new policy that students must wear a mask if they are unvaccinated.

I want to send them a stern letter to let them know that i do not approve of them disclosing private medical history through the display of a mask.

we are in summer break right now so the policy does not yet affect us, however i want to be able to sue them if when school returns if the policy is still in place.

help with with a letter i dont want to sound like a conspiritard or looney in any way. I want to be polite but stern. Im not that good with communication.
