Well, you've heard it said... and I imagine many of you have said it yourself, exasperated with some atheist complaint about prayer in school or a creche scene in front of a courthouse: "It's freedom of religion not freedom from religion."
Well, actually it is both; you cannot have the one without the other. But take heart, since freedom from religion might not mean what you think it means.
No, I am not saying they are both a part of the first amendment and you have to accept a "packaged deal," I am saying it is metaphysically impossible to have freedom of religion without freedom from religion. With one specific exception (which proves the rule) which I will get to.
