> People feel strongly about football, but hopefully not that strongly.

For better or for worse, I’m guessing a lot of people care more about what happens to the local football team than whether creationism is taught in the local schools.

Absolutely! I meant more in the filter bubble sense: I don’t know if I could find a creationist in my social circle, but I could definitely find a handful of football fanatics. So it’s not such a strong feeling as to produce the bubble we see with extreme religious differences.
