Again, silliness. Is it intentional? You keep pretending that this virus is self contained. If you want to put your guests lives at risk, by all means let them know the risks. But what part of you thinks a sinking boat, mishabetach and birkas hagomel are contagious? If you decide to put traif meat in your dishes that’s your choice. If you cook traif meat in your caterers dishes you are involving others against their will.
If a shul decides to have a grouo of people with both immunity and no regard for others in a maskless minyan, let them. But please make sure they sleep and eat thete so the rest of the community does not have to suffer from their negligence. Why is it so hard to understand the difference?
