Only way to not spread this disease is quarantine and testing. Why aren't vaccinated doing that? Why are they so evil or callous that they take risk of spreading it? Why isn't there talk that anyone who wants to protect others must regularly take the test?
Several universities I have colleagues at have regular testing requirements for all uni community members, on top of vaccine requirements. Maybe it could be a more widespread thing, but I think you make it seem more one sided than it is.
