I don't understand what would be accomplished by people across the street and blocking traffic. No one said anything about God not being allowed in the stadium. If God is omnipotent he can't be forced out of anywhere, and that also means he can hear thoughts and quiet prayers. So what is the difference between a moment of silence that gives time for everyone to pray or think or do whatever quiet they wish, and having prayers yelled over loudspeakers if he can hear everyone and knows what is in everyone's heart? I'm being sincere here...the only difference I see is that if there is yelling everyone there has to hear it as well whether they want to or not. I didn't understand it when I was in school from young childhood and I still don't.
If I give my spouse a glance or smile he knows what I'm saying without verbal exchange....why wouldn't God hear the prayers as well without the yelling in stadiums since he's been around forever and knows us all so intimately? Didn't Jesus say he liked things understated and private without show and fanfare anyway? I just don't understand that part besides people trying to get everyone else to pray with them?
If we had prayer time out loud for every other group it would be a big prayer meeting. How is that playing a game? A moment of silence gives everyone a chance to pray if desired.
