But here's the thing - it isn't just sporting events and college classes. Outside of your local area, major precautions are being taken globally. Italy doesn't give a shit about the NCAA tournament. It just ordered all businesses except pharmacies, grocery stores and banks to close. Not to take away freedoms, but to curb the spread of a virus that global health organizations know very little about how to stop from spreading.
And it isn't about college sports fans' "freedom." Sure, you may be willing to take the risk. But think of the ticket handler, the concessions workers, the ushers, etc - most of whom are paid hourly and don't have health benefits / paid sick leave from the job relating to the NCAA tournament. To expose them because you want to preserve your "freedom" as a sports fan isn't just foolish, it's immoral.
