You want to go to a football game, that is a purely voluntary decision.
You now want to demand that everyone else who goes to the game follow your rules
If they don't want to, they are selfish?

The rules will be the rules and no one is forced to go to a game. So to call others selfish because they don't agree with what you want is a bit ridiculous IMO.

Keep in mind as we start to return to normal.
No tests are 100% accurate
Everywhere you go and with every contact you make, there is a chance you get exposed to a contagious disease including corona virus
No vaccine will be 100% effective
No vaccine will be 100% used by the population
You run similar risks of catching the flu and with about the same mortality rate
There are all kinds of risks in life, each of us needs to make our on decisions on what risks we are willing to take
