‘[T]here’s supposed to be separation of church and state in our system of government,....’
wrong. there is no ‘separation’ of church and state in the Constitution: theory or practice. in fact the Constitution assumes and is written under the precedent of Judeo/Christian moral law, which is the basis of western civillization.
thus the establishment clause simply bans any gov’t interference in Christian practice or conscious, without due process.
No, not “without due process”; there is no “due process” involved in violating natural rights at all.
In addition, the Establishment Clause does not include the phrase “separation of church and state”. The USSR’s constitution did include the phrase “the church is separated from the state and the school from the church”.
