Attitudes like yours are the reason people will live in fear for months, maybe years to come. They are genuinely worried, based on strong scientific evidence, about a disease that might kill them (delta is still out there, the next mutation after omicron may already be in the community) yet people like you latch onto one situation (on which the science is not yet clear anyway) and decide that a few tiny rules and courtesies are too much effort for you and can be ditched.
You were willing to go along with restrictions when you weren’t vaccinated. Now you’ve had your vaccine, you are happy to think ‘I’m ok, **** the rest of you’ - you are a selfish **** and most right-minded people would implore you to stay away from them, at football and in all walks of life.
