Speaking of the floor, they wipe it down regularly before, during, and after the game. When sweat or fluids get on it, they have to STOP the game to clean them up. You're 100% sure that the floor of your room is cleaner than that? I guarantee it isn't. Your argument is still invalid.
How often do athletes bleed during a game? And if they do, aren't you aware that they are REQUIRED to come out of the game until they're no longer bleeding? Again, your argument is invalid.
Are they wrestling the ball into the ground? From each other? In volleyball? They're TOUCHING it for a moment at a time, and yes, they ARE swapping out game balls and sanitizing them frequently. Again, HAVE YOU GONE TO A GAME to watch? Your argument remains invalid.
And your athletes are likely screened daily for symptoms, held out of practice if they're symptomatic, and ordered to go get tests if that occurs. Just like everyone was/is for marching band. But regardless - there are FEWER people involved in sports than in band. Period. You simply CANNOT compare a 12 person team to a 50 member band. Your argument, once again, is invalid.
You're saying "damn the torpedoes, full speed ahead" and you're not going to change your mind. Fine. I've listed the reasons you're wrong, and you insist upon being right. Sounds like the occupant of the Oval Office. Good luck to you, and I hope no one in your community gets sick.
