He talked about God in his life, not praying. You still can not comprehend
what you read. And they picked the speaker via who has the best GPA. HE
earned the right to speak.

The school was clearly wrong to prohibit a student from mentioning God in a
speech.
But.....how does this negate the fact that anybody can pray in school at any
time?
Your example didn't involve prayer, did it?

Would seem to me that unless the spectacle was more important than the prayer
itself, people could be praying all over the place and who would know?
