["Thus, when you enter a tax-payer supported institution, your imposition of your religious "truth" on others must be suspended."]

So likewise tax shouldn't be used for anyone to teach an opinion that isn't scientifically proven, say in an English class that Macbeth is a study of the nature of human evil, as it's unable to be proven scientifically, and therefore an alternative viewpoint that it was written solely to make money and please the King is just as true? Wow, I could have got an A in an essay I got a D in, for disagreeing with the teacher's view (which is linked in with the examiner's view). Basically in my English Literature GCSE I could have written down anything, as long as it was a view on the question, and they should have given me full marks, not a C!
