I think that our civics classes have failed the local population. Last week I read so many letters that made me shudder with shame with the ignorance they represented.
If you feel there is nothing wrong with a religious verse being displayed in a public school, then you do not understand the value of the separation of church and state. The same laws that prevent a Christian verse or creed from being displayed before hundreds and hundreds of children also keeps every other religion out as well.
Think about it, what if Parkersburg South High School decided to paint the following, "Whoever recommends and helps a good cause becomes a partner therein, and whoever recommends and helps an evil cause shares in its burdens." (Qur'an 4:85) Would you support it? I doubt you would and thanks to the separation of church and state, you don't need to worry about it.
Please also keep in mind that by not allowing religious sayings in schools isn't the same as promoting atheism. No one is trying to tell kids there is no God or higher power. They are just trying not to have their kids unduly influenced by a religion. Now if the day comes where any school paints, "There is no God," then I hope that some concerned citizens would use separation of church and state to get it removed as well.
