Okay, Gardenlover, how about a group of Wiccans or devil worshippers running out on the field, led by their coach, to pray at half-time? Would your "live and let live" philosophy extend that far?
What if your own child was on that team and was being pressured to join in the prayers, in spite of your child's beliefs, or non-beliefs?
And what if the coach showed real preference for the students who agreed with his religious preferences? Does all this sanctimonious (and probably phony) "praying" on his part extend to all religious and/or spiritual beliefs? Or only the coach's?
The point is, there is nothing wrong with praying. But there are times, places, and situations where praying is appropriate, and those where it is not. For teachers and coaches in public schools, prayer should be a private matter within their own lives, not a performance spectacle. And certainly not an attempt to impose your own religious ideas on impressionable minds. Separation of church and state has helped make this country what it is. Not perfect by any means, but at least it's not a religious autocracy. Let's keep it that way.
