If you see someone didn't wear a mask would you confront them and tell them to wear one?

I would just leave them alone 

No In Australia in Most places you dont need a Mask

Pubs are open Restaurants are Open Clubs are Open

No.

If and ONLY if a maskless person gets close to me would I react. My reaction would not be in words, but my actions would be to briskly move away from them.

I have no time to argue with ignorant people. If they have a medical reason not to wear a mask then they need to stay home during a pandemic or receive curbside delivery if they have no support system to help them with their medical problems! 

I already did it so many times.......sure why not ?

Only a Karen would do that...

No, it’s a free country where I live

No....I wouldnt.  Those people are being stupid for a reason and they believe their reason is greater than the actual facts...meaning they are being selfish. With those people trying to convince them otherwise is pointless. In fact they are most likely to get angry with you for infringing on their personal supposed rights or beliefs.

...but this Covid thing isnt about the One....its about the Many.

I told people to wear musk but it obviously depends on the person who is in front of me. But I always take a minimum social distance from them.

of course....................

I would say something, yes. I have seen a few people before not wearing a mask in shops but someone else told them about it at the time
