They went WHERE and did WHAT!??!!?!

Why would a PUBLIC school allow this to take place when we can't have Parties for Thanksgiving or Halloween IN schools. We can't have prayer in school. We can't read our bibles in schools...but they can take children on a field trip like this while not allowing the rest? I think this is wrong. Tolerance goes ALL directions or it isn't really tolerance! Tolerance that doesn't go in all directions is misdirection and slight of hand in my opinion.
