"The Pennsylvania law, which was passed and signed into law in 2002, allowed schools to opt out of the requirement for religious reasons but not for secular reasons".
All reasons for opting out, save "God told me not to" were not recognized by this law. A myriad of secular reasons, not the least of which are freedom of speech were deemed insufficient.
And that's a huge reason to get upset.
Wrong. "It also permitted students to decline on the basis of religious conviction or personal belief, but required the district to inform the student's parents".
But feel free to be upset. I have no problem with it.
