I understand what you’re saying my friend but you’re missing the point I was making.except that the actual community impact is the people taking up hospital beds. Those are by far and away the unvaccinated so it makes all the sense in the world to have the people showing up to super spreader events be vaccinated. So that if they do get it or pass it around, people aren't dying on the first round of spread, now they can leave there and infect others sure, but because they are vaccinated they are less likely to do so.
Let’s accept your premise: the Virus spreading to the Unvax leads to greater community impact on the health care facilities.
Here’s the problem…
If that’s the case, the Virus CAN spread to the Unvax, at the stadium, bc Vaxxed people can spread the Virus (even if its a lower chance). Meaning, if your goal is what you said it is, then logically you would want to either 1) test everyone so that that no one spreads to the Unvax OR 2) completely restrict the Unvax from attending.
