Prayer in public school is not unconstitutional. It is only unconstitutional if prayer is forced upon those that do not wish to participate. And they all have that option.well right wing nut jobs in usa constantly try to force their views on others, and they wouldn't say they are "politically correct"
examples are trying to bring prayers into public schools (which is unconstitutional)
and trying to teach creationism and/or intelligent design in public schools - which is just plain wrong in every way
A prayer can be anything. Holding up a dollar bill and reading the words "In God We Trust" could be considered a prayer. Most Euro types only cite our Constitution with no grasp of what it really says or its interpretation. The ruling in Engle v Vitale decided that a school sponsored or organized prayer was unconstitutional. Not the act of prayer itself.
