I am an ex-Christian so I will answer from both sides. While we do have a right to our beliefs, there's also a time & place. I see no harm in prayer in schools, however, some do it for a Look At Me type of deal. "Look At Me, I'm Christian, I am taking a stand against public schools secularism." No, not really. Just like a Christian wouldn't want a non-Christian to "make a mockery" of a belief, same holds true here.
Have a prayer in school. But don't make it out to be about you. Because if you are really praying, isn't it to your god & not to man? So why would it matter if people see it for show or not? If god knows your heart, he would see it even if you pray in your own mind, in silence.
Also have to realize that many founding fathers were actually into Deism.
It's up to the parents, mom & dad, to raise their children. Public places should never take the place of the Home.
