Are religions are trying to take over the school systems? Which religions are attempting that?How soon do you expect all this to happen? When (and what) religions are trying to take over the public school system? What are they doing right now that affects any local school in your area?
Besides here online, where else (and when) are you hearing all this talk of hell?
I’ll note the courts have been responsible about maintaining the Establishment Clause in the face of creation ministries and their attempts to introduce religion under the guise of creationism.
