There is no Constitutional 'separation of church and state' PERIOD
There is nothing that prohibits a citizen from praying, chanting, genuflecting, or munching crackers while sipping wine in public. Or that prohibits a whole bunch of people from doing the same thing at the same time.
Proper decorum, however, might dictate that football games are not the place for communion services, but praying for victory, for health, for the promotion of competiton and sportsmanship is entirely proper.
How hard is it for you to tolerate something that over 50% of the crowd wants to do, lasts about a minute, and causes harm to no one?
Can you imagine the hard time they are going to have with "Every knee shall bow; every tongue confess that Jesus Christ is Lord of Lords, King of Kings."
