If you're vaccinated you shouldn't care whether other people in the restaurant are. That's the point of vaccination after all.
And if you're not vaccinated obviously you're not going to be in favor of this new mandate.
The people who support policies like these are vaccin efficacy denialists, petty tyrants, and doomers of various sorts.
And there are good reasons to not want to live in a "papers please" society.
A group of people in a room all vaccinated is safer than a group of people half vaccinated.
The vaccine is not a boolean on off switch, it's a percentage wise improvement over nothing, and it compounds when those around are also vaccinated.
Please provide some citation for this outrageous claim that the point of a vaccine is to NOT provide immunity from infection.
"Vaccines can be prophylactic (to prevent or ameliorate the effects of a future infection by a natural or "wild" pathogen), or therapeutic (to fight a disease that has already occurred, such as cancer)."
That is actually not the point of vaccinations. The point of vaccinations is public health.
