Once the illegal mandates are “lifted” I’ve decided to reverse mask shame. For example, “why are you still wearing that? They lifted the mandate” or “Will you remove your mask please? You know you don’t have to wear that”
Heads will explode and I’ll reply with a smile.
I do it right now by pretending I can't hear anyone with a mask on and I ask them to speak up until they are basically shouting and then I "Okay, okay you don't need to shout".
