Well we arent denying just christians right to prayers. We are denying everyone at schools, you cant just single one religious group out of all of them. Thats like those wacky law books that say that you cant bring a hippo into a post office when the lawactually is against bringing any animal into any public building. As for the ten commandments issue, if you can put the ten commandments in front of a courthouse, you should also be able to put the nine pillars of Islam there too, and people wouldnt like that. If you didnt allow someone to put a statue of the Buddah perhaps, in front of the courthouse and you allow the ten commandments to stay, thats unjust according to the constitution. You'd have to give every religion fair room.
