I have no trouble with that at all. People who attribute good to Satan are generally serious moonbats and never Valedictorians. And even if it happened, they'd be booed off the stage.
I DO have trouble with this:
"We're told students are required to submit their speeches in writing ahead of time and they're told if they deviate from the script at all, their microphones will be cut off."
If ever there was a fascist policy, this sounds like it. No offensive language or obscenities (or else the ACLU would be defending her...) rather just faith in her own religion--speaking for herself. Cutting microphones off because of God sounds more like Soviet era management, not America.
So if she got up to ramble on about how "Bush lied" you'd be okay with it? She was told not to do it ..., she clearly can't follow instructions.
