> Why? Kids are in school about six hours a
day. Why does any of that time need to be
reserved for religious purposes of any sort?

It doesn't.

> Why isn't a religious belief a personal
enough thing that a person can't wait until their
own personal time to practice it?

If a religious belief is truly
personalized, then it becomes something that
a person carries with them wherever they go,
be it work, school, church, or the grocery store.
I don't see any reason why public schools
should need to set aside a specific block of
time "for religious purposes," but neither do I
see any reason for schools to be a "religion
free zone" where a student is not permitted to
engage in activities like prayer, Bible-reading,
or talking about their faith.
