It's not discrimination to want to avoid people who may infect you. Everyone's got the right to do that.
Then maybe exercise your right and stay inside?
Why is it just Covid people have this right to not be infected from or affected by? What else?
If someone is deathly allergic to eggs... do they need to avoid public places where eggs would be a danger to them, or do we stop everyone else from entering all public places unless they've emptied their pockets and had their bags searched for eggs? "People can have eggs if they want to, but don't expect to go to pubs or shops or travel on public transport..."
It's not discrimination to want to avoid people who may kill you with eggs. Everyone's got the right to do that.
That statement is correct, what isn't correct is the assumption that every other complete stranger in public places needs to adjust their behaviour for your right to not be killed by your egg allergy, when you could adjust your behaviour and not be killed by your egg allergy (i.e, imagine if we had vaccines for egg allergies?)
I could keep going... but hopefully you can see the utter warped logic already.
It's like covid is the only thing that has ever mattered and ever will matter again.
