Not to mention (but I will) there is no immunity when people who were infected, show severe symptoms and manage to 'recover' are reinfected by a different strain and their already compromised system goes through it all again. But ... yay team! Football (enthusiasm from the living room couch) is fun and somewhat safe.
Humans are not born with the ability to read and write or to do algebra. If they want to do those things, they have to learn them. Statistics and critical thinking are not skills that humans are born with either. So, if they don't make sure to learn it and get training in it, they don't have it.
The difference between literacy and critical thinking, though, is that people who aren't literate know it.
In this case, you aren't considering one of the most-important things for making decisions: how likely is an outcome. According to data (and there is a lot of it), reinfection is so uncommon currently that, to several significant digits, the probability is zero. Here, you are focusing on something that has been statistically irrelevant while ignoring things that are common and of large impact.
Your statement is equivalent to: "Not to mention (but I will) there is no immunity to getting hit by lightning when going outside. But . . . yay going outside! Going outside (enthusiasm from watching through the kitchen window) is fun and somewhat safe."
Not to mention that you are assuming college football players will get more Covid if they play football games than if they don't. I don't think that's a solid assumption. It could be that if they were living their lives as normal college students instead of playing football games, they'd be more likely to get Covid.
