No shoes no shirt no service.
Forced vaccinations?... Naw.
Limiting "freedoms" when you choose not to participate...happens all the time.
I know I'm new, but I thought I'd throw a perspective. It's like denying people to enter a shoe store because the company feels some of its customers (regardless who they are, where they from, their background, etc) may be carrying a gun. So, the fear that the company (and employees and managers) have is influencing who can go into their store and who cannot.
While statistics can generalize a population that majority of people "will" have guns unless they get a search warrant before going into a shoe store, unless it's the government (depending) or something similar, it's highly unwarranted. Businesses should do their own assessment of risk.
The context is: don't enter this restaurant because you "may" have a disease.
It's based on fear and probability rather than an actual breach in a policy. That's why it's bad because the government and business owners can use (or be influenced by) fear insofar it harms American society. The greater good should be keeping a running society not just currently but as a long-term goal as well. COVID is a current problem, but joblessness is a long-term one. Majority of people recover from COVID but not so much being homeless.
This is just my opinion, though. I have strong ones but nothing criminal.
